Hi Moneybags2,
My credit was too a bit poor not because of Bad Debt just had no credit. Capital One too gave me a Card with a 100 pound credit limit, I have been with them for almost 7 months now. I pay by Direct Debit usually pay in full but when the 4th month came of having the card i was not offerd a increase, I have had the card for almost 7 months now and still never been offerd one, They do say on the 4th statement they will increase, But when i called them they said it's not always on the 4th month sometimes it's longer....
