trying to move adsl line for over a month

I requested Telkom to move a adsl line from randburg to lenasia on the 20 May 2015, the new installation was supposed to have happened on the 4th June 2015. everytime i called to follow up i was fitstly put on hold for over 20 minutes and then told that the technician will attend to the call. this process was repeated about 10 times and till now I am waiting and waiting and waiting but at the end of the month I will be billed as usual for a service that I have not received for the entire month. Telkom this is totally unacceptable for such a large company. your service is disgusting thats why you have over 15 000 complaints.
