Fix your network please

I have been using Telkom mobile for the last four years and I have stayed in the same area (Villa Lisa-Boksburg) for the last fours years plus but from last month. Both my Telkom simcards no longer work when I'm at home. I lost out on a couple of gigs of data I bought. I have a lot of missed calls and calls I couldn't make and to make matters, I use my phone to receive calls from clients. It has gotten so bad, I had to get a third sim from a different network supplier. Everyone I know who is on Telkom mobile and stays at Villa Lisa has the same issue and a couple of those people, I recommended they switch to Telkom, so yeah this sucks. Please sort it out, as I don't want to switch to a different network.
