Fed up with Telkom

I can honestly say I have never come across a more unhelpful and unsupportive company in my life. The products Telkom have to offer are excellent but there back up service is pathetic to say the least. For over a month now our home ADSL has been down. With over 20 phone calls to Telkom the problem has yet to be resolved or even a technician dispatched to have a look at it. Then to top it all off, Telkom have the cheek to send a message with the amount owing for my ADSL line. So why should I pay for a service I'm not receiving??? I'm in the process of moving my ADSL to another, much more helpful, company.
