GE Capital Retail Credit Card Complaint

GE Capital Retail Credit card department,

Credit line increase/decrease Florida

I have - different retail credit cards managed by Synchronicity/GE. All of them with decent limits. I was running balances on all -, with perfect payment history. I paid - of the cards in full and 80 % of the other card. Suddenly, the limit on that card was lowered to $300.00 with no explanation. The other - limits were then raised. This is fraudulent. How would a bank determine they want to dramatically lower your limit on - card and then drastically raise your limit on the others? When I called, they said they did n't have access to the reason, and that I should be receiving a letter explaining why. I received a letter that in so many words stated they re-evaluated my credit and made the determination. This is unjust and I would like to see some action take to bring my limit back up. Closing these accounts would severely damage my credit that is important to me as it is to all of us. Please help.
