Vodacom's bad coverage in Bethlehem area

I have been a client of Vodacom for many many years, but the last few months, since I upgraded, I struggle with coverge all the time. We live in Bethlehem in the FreeState. I have logged several queries, but with now feedback from them. Does not help me to have a new Samsung J7, for my internet is not working as often. When my contract runs out, I am done with Vodcom!!!!! My dad has a MTN contract and have coverage on our farm all the time!!!! Guess who will be my next network provider......Vodacom does not even deserve 1 star out of 5
