can't get DSL line installed

I have logged a request for a new DSL connection at my home, received an SMS saying a salesman would contact me and since then I have heard nothing. I've tried calling the call centre, sending email follow ups and dealing with online chat support but get no response from anyone. I also put a request for a call back on the Telkom sales website and have heard nothing.<br> <br> I'm an existing customer with fully paid up other accounts. This is poor service especially as I'm trying to buy something from you, and you don't seem interested
