Not internet for 4 weeks

We have raised five calls for repair of our ADSL connection over the past 4 weeks, one technician came onsite twice and failed to repair. he even managed to plug the DSL line into the phone connection! on the third call we were assured that a different technician would come and address this, he called and confirmed he would be coming but despite this and anther 4 calls to the call centre we are still without internet. <br> I have done all the usual things, replaced the router, the splitter and the ISP but the problem lies with Telkom
