JPMorgan Chase & Co. Credit Card Complaint

JPMorgan Chase & Co. Credit card department,

Credit line increase/decrease Ohio

I had opened a Chase credit cards in - I called and requested a credit line increase which was granted and it was increased to $4500.00. In - I noticed on my credit report that it stated my credit line had decreased to $3000.00 and is now going over the credit limit. I was in no way by phone or mail notified that this is a temporary credit line increase. I have disputed this with the car company and have gotten no answers they state that they have no phone records that they can provide for me because if they did it would prove that I was not notified of this. I feel I have been illegally bound to terms that I did not agree with I would like all three credit reporting agencies to respond to me in 15 days with proof that I was in fact correct that this was done illegally I would like this account closed in good standings with a - balance because of what Chase has done to me if they can not provide proof of this I feel that is fair I did not want my credit reported negative in any way shape or form as this was not my fault as a consumer and it was illegal I have attached proof on my credit report stating the drop in the credit line and now because my credit is showing over the limit I can not receive any more credit from this company nor any others I have also lost $500.00 because I was in the process of refinancing my home and had to pay for the appraisal and now it will not go through because of what they have done to me
