Vodacom does not care

So I dont know how many times more ill have to phone Vodacom to report our signal problem. We have 2 towers in our area on high mountain points that is densely populated. We cant make any calls, receive any sms, have no internet access and i still have to pay them 5-6k a month. I report the problem and later receive a sms stating the problem is fixed only to have to call Vodacom a week later to report the same fault. This has been going on for 2 years and the last 3 months have been the worst ever. If i phone customer service i get a different number to phone which tells me technicians are busy trying to draw up a report. How much more time to you want to fix this??? People are cancelling contracts and moving over to different networks because Vodacom does not care.
