SunTrust Banks, Inc. Credit Card Complaint

SunTrust Banks, Inc. Credit card department,

Billing disputes North Carolina

Paid my Suntrust credit card in full and on time. Suntrust says is was late and fined $20.00. Contacted Suntrust to disagree and spoke to several supervisors about issue. Fee became larger and larger to $180.00. Then had this reported against my credit, which no supervisor ever mentioned. Have now paid $180.00 ( which was reduced to $110.00 with credits from collection agency ) in full but still have credit issue. Credit score was 845 before Suntrust debacle over $20.00.
