Disgusting customer service

Telkom installed a new line as I placed an order for ADSL and wifi router. They were here on Tuesday to install which went smooth and I was happy with the service up till then. Trevor informed me that I will receive a username and password shortly. Only 2 days later did I receive it. When I called him to query he instructed me to call 10210. When I called there was no answer for what seemed to be a lifetime. I have called 4 times since then and same thing. I have tried to make contact via online chat but the consultants keep on disconnecting me! I have also left my number for a call back 4 times! Still nothing! Trevor doesn't answer his phone or reply to me. I am going to cancel my subscription due to COMPLETE lack of assistance and customer service. Telkom has absolutely NO CUSTOMER SERVICE and couldn't be bothered. I am appalled.
