Capital One Credit Card Complaint

Capital One Credit card department,

Overlimit fee North Carolina

My Capital One credit card was written off -/-/-. The debt was sold to a bill collector. The bill collector ( - ) says they are Collecting for Capital One. I just verified this statement with one of - agents over the phone on -/-/-. I have been paying on this account to - for over 4 years. On my credit reports the capital one bill decreases with payments made to -. Also, the account with Capital One E-CEEDED the credit card limit due to OVER the LIMIT FEES. I never signed anything agreeing to go beyond the credit limit due to them adding OVER THE LIMIT FEES. I want to see my signature agreeing to OVER the LIMIT fees. Is n't it criminal to set a credit limit for me then charge me more, because your over the limit fees, place me over the limit more??. Even though Capital One wrote this off in -/-/-, they have still been collecting money on this account as late as -/-/-. If you look at the decreasing balance on my credit reports for capital one this is evident.
