Telkom charging me for a service they don't provide me!

I have been a Telkom client for over 5 years and have relocated my service 2 times but on the 3rd time, I arranged with Telkom to have it moved the agreed yet never arrived to move my service to my new apartment.

After struggling with their call center on multiple occasions where their systems were down the service technician said that they will cancel my "old service" and I should order a new service for my new apartment, which I did, yet nobody contacted me to arrange installation.

Every month for the last 10 months I receive a bill for a service number that doesn't even exist.

I have called numerous times, I went into a Telkom store twice where once they said they can do nothing and the other time they said I must complain on Facebook.

My account was handed over to a debt collector 2 months ago yet Telkom continues to "charge" me every month. The debt collector has returned my case to Telkom and said they would be in contact, but they haven't been.

I call their call center and stay on the line for over an hour and get disconnected, their website "Chat" function doesn't work, their Form page to send them a message doesn't work.

I am lost as to how to proceed because the bill keeps growing.

Cant, they just provide a customer care or query email address to write to.....?
