Citibank Debt Collection Complaint

Citibank Debt collection department,

Credit card Communication tactics Frequent or repeated calls Texas

I was paying out a credit card with a balance of $580.00. It suddenly had an increase of & gt ; $200.00. I told them it was incorrect, but they refused to listen. This is a Best Buy credit card issued by Citibank , N.A . They are now calling my work about 10 times a day. The front office worker is getting very upset. Everyone has told them to stop calling, but they wo n't. This is serious harrassment.
