Poor Service from Telkom regarding ADSL

Problem with ADSL since 06/10/15. Contacted call centre various times who advised that the matter has been escalated to second tier (technicians). Call centre called back once at 19h50 and our domestic asked them to please call back in 10 minutes as we were not at home. The call centre said that they leave at 20h00 and could only call back the next day. And since then no technician has made any contact with us to resolve the problem. We have been forced to purchase data for almost a month now and will not pay this months subscription fees due to lack of service from Telkom. We have notifed the call centre of this today. This is unacceptable.
