Problems with Telkom Internet account

I had my Internet installed on the 26th of May and it worked for a week. Then the Internet stopped working. I have numerous times escalated that my Internet has not been working that its even been escalated to top management with no help. Today I received a bill from Telkom coming to R1937.00. I was told I would not have to pay because of lost service. I called into Telkom and they said unfortunately I will have to pay for the service and they MIGHT refund me. How can I be charged for a service that I did not receive? My experience with Telkom is so bad not even words can describe how I feel at this stage. No one is prepared to help me. I keep getting referred to someone else when i phone Telkom or the phone gets slammed down in my ear. Still today my issue hasn't been resolved and we are moving onto 3 months with no internet service. I feel that they are in breach of contract by not attending to my complaint. Please can you help me resolve this matter. My Telkom number is ***
