Are there still living, breathing humans at the Call Centre?

I have been phoning the 'so called' Telkom Call Centre on 10210 and 10213 on and off since October 2017 for assistance with downgrading our current ADSL product, but to no avail.

I have held the line for more than 20 minutes at a time and no one answers. I resorted to email, no reply and even went online to try the "Chat to Agent" option - Prudence was unable to assist with my particular query and told me to phone 10213.

Is there any other way to contact someone or to get assistance apart from going to a Telkom Direct Shop (which happens to be very far from my home)?
