We were asked by AMEX to buy a higher level of credit card with Costco which costs $100. a year so we can have better priveledges. We then a few months later got a letter in the mail saying our credit limit has been reduced to $800. due to a couple of reports on our credit report. We have a zero balance with American Express...have never been late...always paid on time...but they say they do not take that into consideration even though we have been members for approximatly 8 years. I did get a copy of my report btw and to me it looked excellent. There was one bad report due to a service that was cancelled by me and is currently in dispute but being taken care of...but other than that everything has been in good standing. Oh excuse me..5 years ago i was late on my mortgage payment ONCE. This is very bad businees especially for COSTCO since I do my business with them and this will be limiting how much I will be spending with them. This is so very insulting to be treated like this. I would like an attorney to take this on.
