I built up $356 rewards with the quicksilver capital one credit card. They they closed the account and kept the rewards. Called and complained for about 2 hours and said they would open an investigation and get back to me. Never heard anything. Not waiting hours on the phone to talk to a manager about it again. Canceled all my accounts and will spread the word about how never to use capital one again since they basically stole money from me. Their defense was that the contacted me before closing my account, but I didn't get anything. After it was closed and I lost the rewards I did get an email, but it was apparently too late then. I'll never get my mo way back. Never use capital one again for anything.
