Telkom the *********s

I recently contacted Telkom to repair my faulty telephone line. two days later I received an sms stating that the fault was repaired. just prior (+- 10 minutes)to that my son called and advised me that the internet had suddenly stopped working. I called Telkom back and told them what had happened-that not only is my telephone not working but also my internet suddenly stopped (this was early in the morning around 09h40am and the weather was perfect)-Telkom advised me that they will resend a technician. approximately a day later I called Telkom back and was advised that my internet cable was damaged by the technician who came to fix my telephone line but that same technician could not repair the cable and that it required the cable repair team to attend, they asked me to bear with them as they would attend to the matter asap. I received another sms late last week advising me that the problems were fixed but obviously Telkom failed yet again. On Saturday the call centre agent assured me that he would send out the first available technician in my area to fix my issues. on Saturday evening I again received the sms "resolved". I called Telkom on Monday and they advised me that they were not going to repair nor replace my cables because they were moving to wireless technology and that I needed to call my internet service provider to assist me to migrate to wireless. my service provider could not unfortunately accommodate my existing requirements via wireless network. I contacted Telkom and pleaded with them to restore my internet because my son relies on internet for his work and as usual they promise to escalate and nothing comes of this. I am at my wits end and I am seriously considering taking legal action against Telkom, can anybody advise me please.
