TERRIBLE SERVICE

I have not been able to receive calls on my telkom number for the past two months. i phoned telkom and logged a case. everytime i phone them for an update they put me on hold for more than half an hour and just come back saying they are still working on it. i also requested someone from telkom to phone me back with feedback over two weeks ago and i still haven't received a call, so today i phoned again for an update they put me on hold for more than 20 minutes and then just cut the call. this is getting really frustrating now. i can't keep paying for a contract when i am unable to receive calls. this is absolutely ridiculous!
