*****sters who refuse to cancel my account, even after proof.

The worst experience I have ever had. I settled my account in full nine months ago and repeatedly sent proof of payment, yet this company has failed to even acknowledge receipt. I have spent countless hours calling, only to be transferred from one person to another without anyone taking responsibility or providing assistance. To make matters worse, they have put my account as "in arrears" which is reflecting so bad on my credit score. At this point they don't want me to cancel. They are the worst.
