<prompt> Human: So I had a limit on a debit card that I forgot about when purchasing a product. Tried to pay for the product to which only 50 was chargedthats the limit. I told the cashier to cancel the transaction so that I may take the cap off so I could pay for the product. I pay for the product and ask a manager if the transaction was canceled for sure to avoid being charged the unnecessary 50. She assured me it wouldnt go through. I did so and I check the account history after the transactions and it says Ive been charged both the 50 and the 63 for the actual product. I raise a claim with my bank to which they issued me a temporary credit. Its been about 2 months since the claim was raised and now it is closed. I now have to pay it back because Walmart has denied the transaction due to lack of proof. What should I do to get the money back?  <response>: Former Walmart Manager here. First call 1-800-walmart, and lodge a formal complaint. Print a copy of your card statement, obtain your receipt and take it to the service desk. With the receipt they can look at their Electronic Journal basically a digital copy of all transactions for that day. If they still keep denying you. Keep calling 1800 number, it will start at the store, then elevate to the market level, and god help that store manager if it gets to the Regional Vice President.Edit: sometimes even though the card does not go through the debit card company will put the transaction on hold for 1-3 business days
