Ongoing credit card fraud that Barclays failed to sort for months ( had to contact them multiple times). They failed to notice odd spending on the card. They failed to ring me back when the phone line disconnected mid conversation with an operator. I put in a complaint and was told they understood their failings. Then once appeard to be sorted they cancel my credit card, no reason given, and an incorrect letter sent prior stating the wrong credit card number. Despite 14 years of having a credit card with Barclays and no issues of paying it off, multiple loans from Barclays all paid off on time or before with no issues and they treat me like this. Now I'm worried this will affect my credit rating.
