<prompt> Human: On February 13th I made two different transactions from Walmart. One was for a few things of candy, and it showed up correctly on my online bank statement, for 4.55. After that I went to get my friends in the electronics section and saw a card I wanted to get, and bought it along with a pack of gum. The total couldnt have been more than 5. So within the next two days I check my transactions and I see a charge for 188.52 after the 4.55 charge, both from Walmart. I call my bank Navy Federal Credit Union, and file a claim immediately but theyve told me that without the receipt I might not get my money back. They just got back to me, so I plan on going to Walmart today and seeing if I can fix it. Also, the lady in front of me had a declined credit card and just all of a sudden walked out with her groceries, a full cart of them, and Im wondering if that accidentally got put on my card, although I remember the total being the correct amount on the screen. Any advice is much appreciated, thank you!tl;dr Bought 5 worth of stuff at Walmart, got charged 188. No receipt. Lady in front of me walked out with a ton of groceries without paying for them which could be the issueAssistant: Do you think Walmart can pull the transaction up? Can you get your CC statement online and see if theres a transaction code that Walmart can cross reference?Im a little bit surprised that Navy Federal would say without a receipt youre screwed. In my opinion, thats a fraudulent charge. You might want to call them back and phrase it as such. Theres been a fraudulent charge on my card. The last proper charge was xyz and this date. Then let them take it from there.Human: Thank you for the response. They didnt quite say I was screwed, but they said without knowing the correct amount I paid, they werent sure if it would go through.  <response>: You will likely have to go the bank route for this. I dont see walmart just reversing a charge like that on your word.Dont contact the bank with its the incorrect amount, I bought something else... go with its a fraudulant charge. Dont mention this 4.55 charge you should have. This is a fraudulantmistaken charge for 188.52. That is all you care about. The less you say the better. Now if walmart wants to come to you for the 4.55 then you work THAT out with them. That is between you and walmart, not your bank to worry about. Your bank only needs to worry about this 188.52 that wasnt you.The 188.52 is fraud or a mistake, you want it taken care of, that is all you care about. The less you talk, the better your chances.
