Citibank Credit Card Complaint

Citibank Credit card department,

Credit line increase/decrease Oregon

I had a $2000.00 credit line with Sears. I always pay my card timely ; in fact I always pay my account early. I did so in - pay - payment early. I had requested long before that my due date be changed to the - I believe so there would be no chance of my payment being made late. It was agreed to do this, however, they never did and my payment for - or - was a day or so late. I immediately contact them by phone to resolve the matter. Later, they took away my $2000.00 credit line for their own mistake. I called in about that and spoke to repetitive women who told me to write in to their very department so they could deny me again. I sent a fax to the director of that dept. but never received any response back. I just tried to place an order and only 2 of the items were shipped and I received a notice that for my convenience the other items are in my cart? What Sears has done is ding me for their own mistake and though the women I spke to agreed that this was Sears ' mistake, they would not undo the retaliatory, unlaqwful treatment that I received because of their error. I just need my credit line reinstated and for whomever restricted my account unlawfully in the first place to keep away from my account at all times. This was their mistake, not mine, so I should not be punished for it! Thank you.
