I have had this card for 2 years, spending a lot, receiving a lot of cashback, and paying back balance in full on time, making no money for Capital One.
A few days ago, I received a call from India (where else) stating that card security had been compromised, allegedly attempts by thrid parties to commit fraud (no evidence produced), stating 'someone may have been arrested with my details in possession. I verified recent transactions (no problems).
They had already closed my account, and I will have to wait for a new account and card. How inconvenient is that, I cannot put petrol in car, and cannot get to work. All requests to reactivate account were denied. I think it is standard practice to contact customers before closing accounts.
I suspect that a staff member has stolen details of many cards, and Capital One are simply protecting their own interests, or they are simply trying to get rid of unprofitable customers.
I have demanded a full, written, credible, explanation of the circumstances, and compensation for inconvenience and loss of earnings. I will keep you posted, and invite comments from others who are having similar problems.
