Vodacom does not reply nor does anything

I have been with vodacom since i got my first phone, same number and renew my contract every 2 years for the last 25 years. Now i have no signal where I always had service. We sitting in a area that only receives reception from one tower because the mountains block the rest. Now for the last 3 month the tower is not working and does not matter to who you report it, nothing gets done. Now i only rely on my private internet for wifi. Its the only security we have and the only way of communicating thru wi fi. Rumors are that the tower is off because of the rent that vodacom has not paid for years where the tower is situated. Why do i have a new contract and still with vodacom if there is no attemp to reply on why there is no signal nor attemp to repair or sort out the problem. Its not just me, the whole area is down where we live and many are complaining. This will be my last contract with vodacom after all these years. The tower im refer to is know as the tandjiesberg tower just outside Graaff Reinet, Eastern Cape
