5 Months Due, No Service!

Credit card division and the contact centre rating should be half a star. 5 months later still no solution regarding the credit card account. Worst customer experience ever had by far. I fail to understand after countless emails and telephone conversation as to why am I still in arrears, by date the credit card account should be closed. It is sickening that as a bank you are turning a blind eye and not offering any assistance. Who is responsible for the collections mailing address, such a perron should be released from that task, or such computer should be destroyed as it serves no purpose.
