slow internet

I live in Dersley Springs, since 21 April we have had extremely low internet or call signal in our area, I have reported the issue to Vodacom who finally came back to me yesterday and their response is ridiculous. They need to do repairs to the tower but they do not have access to the tower!!! they also cannot give me an estimated time as to when this will be fixed and they offered to add 3 gig data for my phone, which is ridiculous as I cannot use it. So my Rain wifi is also coming from the tower and as a result both are slow, now is the time to change to fibre and different service providers
