Vodacom Tower

I have called Vodacom over the past 3 weeks to advise them that our Vodacom tower is off, and it's been a month every time I call, they say that the request has been escalated and the technician are working on it and that I will get a call from one of them till today no call and no one has come out to check what the problem is this is very poor service from Vodacom cause we affected unable to make calls or receive calls cause of the signal.
