I applied for a credit card at a bank and told them I had two other credit cards with different banks. They would only approve my credit card application on condition that I closed the other two cards; the reason being that they thought I wouldn't be able to afford the repayments in the event that I maxed out all the cards. So I agreed, and closed the two cards.
However, I'd actually be pretty keen to reinstate one of the credit cards that I had to close. Is there anything wrong with doing that? The way I see it: when I request to reinstate it, they may ask what other lending I have and I'll tell them. They can decide whether it's affordable or not, or they could drop my limit. I just don't want to do something that looks underhand.
