Citibank Credit Card Complaint

Citibank Credit card department,

Credit line increase/decrease California

On -/-/- citicards pulled my credit report and approved me for a credit limit increase on my credit card from - to -. There was negative information on my credit report at the time ( a bankruptcy filed -/-/- ), however, my credit limit increase was approved. Since that increase in -/-/- I have used my account in accordance with the terms & conditions, however, I am now being turned down for increases because of my bankruptcy on my credit report. With this in mind I feel unfairly discriminated against.
