Bad Service and Useless Call Centre

I app**** for an ADSL line on 16.03.2018 and paid a deposit and up until today I still don't have my line. Every time I phone Telkom (10213) I get told "it's with the cabling department" and I must just wait for them to call me. I have left numerous messages for a manager to call me. I have also sent emails and left messages on their website but don't get any calls or replies. I am a new customer and this is the kind of service I get. I will never refer anyone to Telkom.
