BAD service

I Was on debt counseling, however finally i could pay of my edgars account, doing so i contacted the edgars legal department and requested a settlement letter. I paid the exact amount stated in the letter. Edgars legal department requested i send proof of payment and once the money cleared in 24/48 hours i could contact them again for a paid up letter. I did receive my paid up letter but i also wanted to close my account- again i needed to email them in writing that i want my account closed so i did. A month later i receive a bill stating that i over paid NOW TEL ME WHOS PROBLEM IS THAT. i contacted edgars once again asking what now i want my account CLOSED-I was given an email address of the consultant to send all my documents to including my banking details so that they can refund me the money -as i was told i did send them an email, 2/3 weeks later i receive an email from edgars stating that they over paid and i need to send my documents--- SERIOUSLY.And i again received a bill for this month after re-sending my second email stating in every email i want my account closed. And now there is money deducted from the overpaid amount because the account is open. FUMING
