Telkom and its *********** workforce

We have had one of the worst experiences with a service provider one could have. Telkom sales reps rock up at my place selling fibre. We decided to take the deal 20mb for R804 per month. 2 weeks later the line was installed but we couldn't connect to the internet we called in and the customer care agents did there checks of which none worked for 2 weeks we called in every day spending hundreds of rands in airtime and hours wasted of my life. Each time we called in a different person was on the otherside and even tho we told them we have done these trouble shooting steps they persisted with wanting to do it. After requesting for a technician to come out we were refused. I forced the last consultant to log a ticket and give me a ticket number for a technician to come out. Its a month later no one has come out. My line hasn't worked a day and Telkom has the ordasity to invoice me and then invoice me R1066 instead of the R804 as signed on the contract. Telkom has some of the most *********** people working for them and their systems do not work. We have put in a request to cancel the line with no response. They make it so difficult and their service sucks. Someone please help
