Uber Eats review: Order placed 9/7/23 with 40% off promotion to be delivered 9/8/23

My name is Jacqueline Carbonell the email on my Uber eats account is [protected]@gmail.com and my number is 646/296/2641, this complaint is in reference to an order placed through Uber Eats at Bazaar Foods on 9/7/23, I used a 40% promo code that was on my account and my total was $55.86, I scheduled delivery for the following day 9/8/23 10am-11am, I received my order with no issues, then later on in the day I was going to place another Uber Eats order only to have an "Alert" on my account stating I'm owing $31.43 and I'm unable to place any further orders until amount is paid, I immediately checked my account and the receipts and to my surprise there were 3 "adjusted" receipts all 3 receipts were in total amount of $87.93 and the initial receipt with the "$55.86" was erased/deleted, I called Uber Eats Support at 800/253/9377 and explained it was an error on their part as I used promo code 40% off, rep "jane" I spoke with claimed there was no promo, I sent a screenshot of my bank card with the pending amount of $55.86 and was told to provide screenshot of promo code, (I could not provide a screenshot of promo code as once code is used it deletes from the account) I spoke with 3 different reps and 2 managers who provided no help whatsoever! they kept stating that $87.93 was the correct amount as there was no promo, I sent all these reps the same screenshot with proof of the initial purchase amount, It seems they went into my account and literally deleted the initial transaction and replaced it with no promo code and are now asking me to update my payment and pay the $31.43
