Tractor Supply review: Poor customer service, overcharged for clearly marked discount item

I was a customer at the windham tractor supply 476 Boston post rd in north windham Connecticut on Saturday May 8th around 6p.m. I had called ahead to ask for 5 fifty pound bags on barn lime but as I arrived and noticed a line I decided to shop around a bit and when I brought my purchases to the register I told the woman working (Rayann) that I had 5 bags of lime waiting for me, she wasn't sure at first but contacted her fellow staff members and a man (Joshua) at the center counter towards the back of the store said "they are here". I asked the Rayann to scan them for me and we walked back to them and scanned one bag and went back to the register. I used my family's tractor supply rewards card as my family has been a loyal supporter, even shopping at stores in different states and always being happy with our purchases, and I proceeded to pay with my debit card. After completing the transaction I used my shopping cart to retrieve the bags of lime from where they lay at the middle of the store and that's when I saw the sticker showing a bag to be "reduced price" and showing a yellow sticker clearly marked $2. I then looked at my receipt to see if the price was shown discounted for one of the bags of lime and quickly saw it was not. It was then I asked the woman standing in the center counter area that was previously occupied by Joshua if I could get a refund for the price difference. I felt her attitude immediately about what I realize is a small amount of money and a trivial complaint but I was unprepared for her responses. She stated I could get 5 fresh bags of lime. I told her I was ok with the ripped bag I just wanted to be charged the correct price. She continued to offer replacement bags which I declined. She perhaps didn't understand the fact that when I called they clearly told me they had 8 bags total and would set aside 5 for me so a total replacement of the 5 bags would have been impossible at the current time. Alissa continued to have sarcastic and bad mannered retorts to my trying to explain the situation. I was repeatedly told I was incorrect that those bags were specifically put aside for me after I called and that "that was where the lime lived" (although I was put on hold for long enough when I called to assume that the person who answered (Joshua) was going to check your inventory and set them aside for me). Alissa told me she was the manager when I asked for them to join our conversation but Rayann told me as I was leaving that Joshua was the manager so I'm very confused about who was telling the truth in that circumstance. I had terrible anxiety while trying to explain my situation to Alissa and was having trouble breathing and speaking and wearing the mask was not helpful either at the time. I told Alissa she almost gave me a panic attack in front of customers and Rayann and Alissa said"you almost gave me a panic attack, I can feel my heart racing."
This type of schoolyard type behavior of saying she was just as much in the same situation as me continued with everything that I said, belittling my concerns in front of staff and customers and in no way made me feel the typical "the customer is always right attitude" which is so common is business today. I was not made to feel my loyalty and purchases and current concerns were of any importance or significance by the employee Alissa typified but her response to my saying "you don't know what I've been through today" (my mother had just been in a car crash and her best friends funeral was this morning) by her replying "you don't know what I've been through, nobody knows what's going on with other people", she said this again at the other register as she was ringing another customer out (very unprofessional) while Rayann was processing my refund. Alissa stated "I'll give you each bag for two dollars if that will make you happy" with a sarcastic and rude tone of voice which I politely declined and again stated that"I just wanted to be charged correctly" Rayann went about reprocessing my payment and returned me $6.85 which I thought was too much as I had stated to Alissa and Rayann back at the register that "5 bags times $3.29, that's ok, one bag was ripped and is discounted to $2 so I just want my $1.29 that I'm owed" but I guess my concern was again overlooked and I am now looking at my new receipt and I was charged the $2 each for the 5 bags so they returned $6.85 without needing to and against my wishes. I have high value in honesty and integrity and abide by a high moral compass and am courtesy and respectful in all manner of business but what I experienced today really made me feel like not returning to tractor supply ever in the future, I actually said this out loud to Alissa and got no response or sincere concern about that which was really the ultimate show of lack of respect for me as a customer, I also feel the insensitivity I received when informing them I had anxiety was unacceptable, Alissa repeatedly belittle my concerns with her childish responses. My family and many others suffer from a diagnosed medical condition and should never be made to feel so unimportant as a paying customer let alone the standard common decency as a human being with medical issues. I'm sure your company does not appreciate the behavior of your employees today and wouldn't want me to contact the local newspaper about insensitivity and discrimination experienced by someone with a medical condition at our local store here in Windham Connecticut. Honestly until I hear from someone at your company I can't continue to risk shopping here again.
Attached is one picture of my original receipt, I will send the updated receipt as well if I can.
