Everyone I know who has had a Chase card has had similar problems.
I had my minimum payment doubled. If I had been on a limited budget it could have driven me into delinquency with its attendant late fees every month. If ever a system was DESIGNED to drive you into financial insolvancy, this was it. I paid that card up in full and closed it immediately. My wife's interest rate went from approx 7% to 20% for no reason - CHASE again! When she phoned them, they said that they could do it under their contract terms - so they did! It will be paid off and closed next month!
Meantime, all the WAMU branches which were stolen by JPMorganChase as part of their successful bank robbery of WAMU are being redesigned into East Coast banks from their previous hip West Coast internal layout. What a wonderful use of money in these troubled times! Why, those kind buttoned-down, uptight, Harvard-trained thieves are spreading the wealth to the local builders. It is very important for a dog to look like its master!
And now, we hear, credit card companies are looking at charging credit card annual fees of $29 - $99 on accounts that pay off in full every month. They have to make a profit you know - and it's legal! These guys know that the Government may huff and puff about the capitalist system, but they are protected - they are too big to fail.
So did everybody else with a credit card. It was a law passed by Congress.
