Worst company ever!

Ref number : Z ********** .After a big rain in Bloemfontein in the beginning of feb, My internet adsl line was not working. I contacted telkom about the problem and they sent a technician to tend to the problem. The first problem with that, the technician with the name of Khothatso, could not make arrangements with me to meet at my home at a convenient time that will suite us both. He came to my house without conformation of a time and said if he does not work on the problem then, he will leave and I will stay without internet till they will want or be able to help me again. I arranged for my wife to open the gate so this stranger can work at my house and fix the internet. When he was done and went on his way, the internet still did not work at all. I phoned telkom 5 more times and nobody phoned back or came uot to fix the problem. I phone them after 2 weeks and cancelled the line. I lost 63GB of data at Afrihost because of this. When I phoned to cancel and asked what they will do to refund me because of their fault, the just said this is not their problem. the last time I spoke to somebody at telkom was on the 21/02/19 and it was with Malusi at 13:30 and Nomvula at 13:45. They still haven't even try to find out why I cancelled or to see if they can help with my data that I lost because of them. Is there anyone I can speak to or email with my complaint?
