On XXXX XXXX, Citibank contacted me about a decrease in my credit limit ( a decrease of {$2500.00} ), due to items that had appeared on my XXXX credit report, which stated that if the credit report changed, I could have them reevaluate the decision within 60 days. On XXXX XXXX, I contacted them and they stated that they only could request a credit limit increase, there was no process for disputing their previous decision. They requested a credit limit increase and the increase was denied, and were not able to provide me with a reason. Their decision was triggered incorrectly and they have unfairly prevented me from reinstating my prior status with them even though the factors that prompted their decision have been proven to be in error.
