Amazon review: 3 complaints to bbb and over 40 emails to amazon and still this issue is unresolved!

I have been trying to receive refunds for 3 orders, 112-0924739-5194648, 112-0524433-3857026 & 112-1977016-4013002. All 3 have been returned to Amazon but every time I contact Amazon about a refund, I am lied to by an associate or supervisor. All 3 items were purchased new but arrived used with an LPN barcode attached. No one at Amazon has heard of these barcodes even though they're the ones who create and attach them to items. Then, I'm being told the items are still in transit when all 3 have tracking numbers and show they've been delivered to Amazon for weeks. Here is proof of the blatant lies I'm being told:
"Hello,

I am Mahendra from Amazon.com.
I'm writing in response to a complaint filed on your behalf by the Better Business Bureau BBB - I've provided the BBB with a copy of this message.

Upon reviewing the complaint details, I see that you are referring to the order's #112-0924739-5194648, 112-0524433-3857026 & 112-1977016-4013002 regarding refund for the items.

Based on order details, I see that the item are still in transit and refund for the items will be issued only once the items marked as received at our fulfillment center."

So I will be filing a charge back with my bank and canceling my prime membership. Amazon used to have OK customer service but now it is a joke as I'm sure you're well aware with all the lawsuits and complaints you receive.
Refund these orders to my original payment method and let me be done with this ridiculous situation. I have filed 3 BBB complaints about this and continue to get the same lies as a response. Don't sell used items as new and don't lie about it and hold refunds hostage. Shouldn't have to let you know that's a [censored]ty thing to do.
