Credit Card Sharks

I run a small business and like most small business owners have business credit cards. In the recent months the increase in interest has been brutal to say the least. In one month my Advanta card interest went from 7.99% to 25.08%. I called to find out why the increase happened and to try to reduce the interest and they said it was just across the board increases. I asked if the fact that I have great credit and make payments on time was taken into consideration and they said to just call back in 3 months but for now nothing could be done. As far as I am concerned this is just like loan sharking only these credit card company get to bully you in broad daylight! This is one business where government needs to step in and put a limit on the interest a credit card company can charge! What is the point of having good credit if it doesn't make any difference on how the credit card companies make decisions. I had 3 credit cards accounts with Advanta as my husband runs a business and I also am active in real estate investing and used one for that business as well. I have moved my charges from two of the Advanta accounts to our Chase card and a credit union card with acceptable interest rates. I am still working on moving the charges from the last account and when I do, I will not be using or recommending Advanta. I was happy with their services when I opened the accounts but the recent disregard for me a customer is unacceptable customer service.
