In the XXXX quarter of XX/XX/XXXX, my credit score was impacted adversely due to a medical bill that was reporting adversely in error to the Credit Bureau. This bill was paid in full ; however, the medical provider posted the payment to the wrong account which resulted in the error. During this same time, I made a significant large payment to Citibank. Within days of making the large payment, Citibank reduced my Credit Line from what was over $ XXXX to my revolving balance amount. When I called about the reduction I was told it was due to my FICO. Between the medical bill and the CL reduction, my XXXX decreased over XXXX points. I researched the issue with the Credit Reporting Agencies and found the medical bill error. This was corrected on all XXXX Credit Reporting Agencies by XX/XX/XXXX. My FICO then increased over XXXX points. In XX/XX/XXXX, I had contacted Citibank about restoring the line back to the original limit since the reduction had effected my score as well. I was told that they could not give me a reason why and I would have to wait until I received a letter. I requested to escalate the issue and was told that no one could take my call. This is unacceptable and it is a bank Regulation to provide a reason for adverse action. I am currently making over $ XXXX a year with $ XXXX in income through a XXXX property.I have been actively paying down my accounts in the past year. I think that this treatment is unfair and breaking the Regulations set forth. I wish to have my credit line restored to the original limit with no intention to use, only to improve my credit score. I am in the process of buying a home and this issue is preventing me from obtain the best avaliable option. I have paid my account on time since opening the account over XXXX years ago and I have alway paid the fees associated. Please consider restoring the Credit Line and address the Regulation violation. Thank you!
