Citibank Credit Card Complaint

Citibank Credit card department,

Cash advance fee Illinois

I obtained $1000.00 cash advance x - on -, -, and -/-/15. When I received my statement in -, 2015, I immediately repaid the $3000.00 plus associated fees. Furthermore, I have paid my account in full every month in 2015. For some reason, citibank has billed me interest on the -/-/15, -/-/15, and -/-/15 statement, totalling about $240.00. Furthermore, the current statement shows the balance of the cash advance as INCREASING as interest is accrued. But the cash advance was PAID OFF IMMEDIATELY, along with the entire balance of the card every month.
