Telkom ignores clients

For 1 month now I've been trying to make contact with Telkom. They stoll have not contacted me, even tho they say they will. How can I take this problem to the next level of complaints? I'm wanting to get the fibre line within my area. I've been pre approved over a month ago. So all I'm wanting to do is upgrade my line and pay more for a service, just for the speed. ..but they don't want to contact me. This is the poorest evel of customer service I've come across in a while. <br> <br> I assure you that no one will contact me from Telkom! So please hellopeter.com, can you help me?<br> <br> Emile
