I have many cards mostly to fund my business. It is easier to get money this way then with a bank I have a Wells Fargo card with a 12,000 limit I used 10,000 for 0% balance transfer for a year. After the year it went to 22% so I transfered to another card $8000 of it. My balance with them is less than 2000. I got a letter saying that they are reducing my available credit amount to 2000. I've never been late I paid the minimum + a little more because I'm snowballing some other card. This is goofing up my credit score it there anything I can do
Unfortunately, banks are reducing credit limits like this often these days for customers that carry high balances and then pay them down all of a sudden. They're trying to reduce their exposure whenever they can, and there's not much you can do about the reduced limits. Like jj said, you've got to keep your credit utilization low - preferably around 10% if you want to see an improvement in your credit score. It counts for about a third of your overall FICO score. At the very least, try to get your CU ratio under 30% for all your cards.
