Nomsa Mokoka

I have a problem it my internet connection, from last week Friday, I have tried calling them to report the matter, but I cant get help. So they asked me to call them in the afternoon hen I get home I have tried, but the problem is they keep you waiting for so long until you airtime is finished, yesterday I bought R60.00 from Vodacom I tried to call, but I waited until I was number 3 and they put the phone down on me, this is very frustrating because they debit my account every month (***5) for ND Mokoka the number I'm using is *** as my ***5 number is not working please I need assistant urgently as I cant go work from the office everyday.
