I had a Citi Mastercard Platinum and before that another name that was fixed 9.9 % when I called them about another issue the man encouraged me to switch to another type of Citi Master Card that offered restaurant etc advantages, a sales pitch ;, to obtain a Diamond preferred Mastercard, keeping the same number. What he failed to disclose was that by taking this offer I lost my fixed rate to a variable rate. I want my 9.9 % fixed rate back. They also changed the amount of time i was a member with them. These things affect me in that our USA and global economys could go bad at anytime and as a variable rate a credit card company can request market rate which could be exhorbiant. I am worried about them being able to change the rate on me at will. Also, and/or that any of this could effect my credit rating which is extremely good. Please help me get my fixed 9.9 % rate back.
