A fraudulent transaction of $68.81 was initially charged to my credit card on March 22 2021 to Deliveroo.co.uk which is a food delivery service in London UK. I would never order any service from them since I live in Palmdale, California and they only deliver food to customers in London UK. The credit card company noticed this to be a questionable transaction and so it sent me a text message asking me if I authorized that transaction. I immediately replied NO and so they told me that they would block the transaction. So then I canceled the card and ordered a replacement card suspecting someone got a hold of my credit card number. I contacted Delivery.co.uk and they told me that they never made that transaction nor do they have any records of me or my credit card number in any of their databases.
To my surprise, the next day (March 23, 2021), not only did the transaction still show up in the transaction list in their mobile app, but the amount changed from $68.81 to $96.88, which should have been impossible since they already texted me that they blocked the transaction. Furthermore, I canceled the card the previous day so the card shouldn't have even worked. Then it changed again on March 26 to $95.56. That’s when I realized that it was the bank itself making the fraudulent transactions since the amount of the transaction can not be changed by a merchant for the one transaction with the same transaction date.
