All CC companies are the same. I had the same crap with Barclaycard except worse...
MBNA have been good to me. But only in so much as I've never had a problem and gotten forced to a call center in India etc.
Barclaycard was so F--ING annoying because none of them understood my complaint letalone resolved it. After written complaints I got through to a UK person at long last, but she was unable to fix the mistakes previous call center staff had made to my account and each attempt was a risk at damaging my credit rating. In short it'd been f-ed up so badly that even senior UK staff couldn't do anything about it. I closed the account.
I only applied for it in order to take a balance transfer offer up - and have now lost 6 months in interest on the card I wanted to transfer from as I am not in a position to clear the debt and don't want to risk applying for a new card as it might get rejected. (Too much credit in X time period.. )
So. They're all as bad as eachother.
