I spent about £95 on a big shop 3 weeks ago. I went through the scan and go. I had my two boys with me (2 and 3 months) and I paid using contactless. I didn't grab the receipt which I didn't notice until I got home and was annoyed because the supermarket had an offer for money off voucher if you spend so much that I had intended to grab but only realised I didn't have it when I got home.
I budget everything and wrote the shop on my budget app straight away so I noticed the discrepancy on my account within a few days. I thought it was just taking a little longer than normal to process but 3 weeks later there's still no record of it. I've checked every account I have including my husband's just in case I had his card though I'm certain it was just my day to day debit card. The only thing I can think is that the payment didn't process and I just didn't notice and walked straight out. But surely someone would have stopped me! I remember a friend telling me once, with a tiny shop, just a quick lunch on the go kind of shop, this happened to her once and she was stopped in the car park by security. I don't understand how this has happened. I wouldn't have been quick to leave because my 2 year old moves at a snails pace.
If I go and talk to customer service in the shop will they believe that is was a genuine mistake and just let me pay for it or will I get in trouble?
