Account in arrears - noone to contact

I have a Telkom account, which ran in arrears because I was not receiving any bill even after requesting it several times. I went into your mutual park branch asking for the account to be debited and they advised against it. I then get an sms asking that I make contact to arrange to pay, I have called the number 23 times from a recorded line, and I can prove it, got through twice to someone who wasn't handling my account and was promised a call back. My account is now suspended and I still have no help.
