Account paid up, but no feedback from accounts.

On the 16th of February my account was settled by a third party and on the 19th I forwarded the proof of payment to accountsjhb@edcon email address. No feedback was received and on the 28th I called the call centre to see whats going on, because I requested a settlement letter as well as a confirmation of account closure. The friendly call assistant asked me to please resend the the mail but the include the address for ********** I did that on the 28th once more. Today is the 09th of March, I have not receive any feedback with regards to this query?!

My account was in arrears, and I was called constantly and threathened. But now that the account is paid up and I am requesting some assistance i am being ignored?

Really frustrated at the moment.
