NO SIGNAL AT MY RESIDENCE FOR 10 YEARS

I have been a loyal Vodacom customer for many years and spend a lot of money with them every month. I use my phone and data for business. I just made a complaint on Hellopeter about SMS's which weren't working which was resolved quickly and am hoping this will receive the same attention. I have complained about this several times in the past, given reference numbers and promised this will be looked into but it has never been looked into and never been sorted out. I barely have any reception at my residence and often none at all. I have to go find a spot in my garden or a particular room in my house in order to make and receive calls or use data services. I have had this problem since I have been living in my house and its just worse today than ever before. We are talking about 10 or 11 years. I am really fed up with this considering how much I use my phone. My contract is due for renewal and I will be moving to MTN if this is not resolved immediately.
