****ed off!!!!! And disgusted...

I am so ****ed off and disgusted with the level of service from Telkom, I have been trying to get a service from them since middle of march, been in contact with them ever since spoke to so many consultants and they always making notes, sending it to different departments but still nothing happens, I am using between 50- 100 airtime every time I call and that is like three times a week, first you hold on for 30 minutes before some one actually picks up, I called this morning waited for 36 minutes then someone picks up asked them to call me back and they say they can't because its an inbound call centre they went to get a supervisor but once again the the supervisors offices are empty they not in, he wanted to log a call for the managed to call but still needed to take my details down after I verified all my details with him already...and guess what my airtime cuts...I am at my wits end now trying to get a freaken service from them...I have been pushed back and fourth with no help at all...where to from here....one ****ed of person...
