Very bad service from Telkom

In February 2018 I app**** for a adsl 4mg line from telkom online. They contacted me and took all my details and then said they would let me know when the installation would be done. I never heard a word from them agail and I just left it. In July they were at the house but nobody was home so nothing was installed. This was 5 months after the application. They arrived with no notification that they were coming. Now they are billing me for something I do not have. I phoned Billing and they put me trough to sales to cancel the order. Sales told me they cannot cancel the order and gave me the email address **********

I sent the email to that address and it does not exist.. I phoned sales again and was told there is no such email address that exists that I can use to cancel the service and that there system was down and they could not help me. I must phone back. I dont have a telkom line so I am phoning from my cell phone so am paying for the calls. I have been on the line for 45 min.

The reference numbers I got was from billing ********** and sales was ********** .
