Hellkom *******

My Telkom account has been suspended for 5 months now because of Telkom's incompetence. I have begged and pleaded with Telkom to resolved my account. For 5 months I have had no internet and I am still being charged the full amount. I have sent escalation emails to every Telkom email address possible and still no response from Telkom. What is the next step??? I cannot keep being charged for internet I am not receiving.
