worst customer service, Looking for new provider.

I app**** for an adsl line on 2 August 2017. On 4 August received sms with e-mail account and password. On 10 th August phoned to ask when will installation be, and that they must make an appointment. Assured me will contact me. On 11th August being at work, son in law phoned and said Telkom is at front gate, ( without appointment). I told him to let them in I am on my way, taking leave. Still travelling home, Son in law says they have left to go set up a line for me, will be back. After waiting from 9 to 11, I phoned. Telkom assured me they will come back as installation was scheduled for that day. Phoned again 14h00, again told will come before 16h00. 16h00- No one still, once again phoned and lodged complaint with Singiwe 997560. Waited Saturday, no feedback. Phoned Monday, told installation was not scheduled for Monday, and they have 3 installations already. Being behind, how is this possible?Already Wednesday and still not contacted. Pathetic I tell you.
