No network coverage for over a month

I go for days without network. Iv called the customer care line, the mtn network coverage line, all I’m told is that there is a fault with the towers in my area and it will be sorted out soon. It’s been over a month. I pay R1700 a month on contract only to be left stranded and without coverage. I’m missing work related calls, my packages that are being delivered to me are being turned back, friends and family can’t get ahold of me. As I type this I had to use Telkom Wi-Fi. I’m so over this. I don’t want this contract anymore because I’m paying for nothing. I stay with my 2 month old son what happens if God forbid I have an emergency. I can’t even get ahold of his paediatrician as the need arises. I’m just frustrated and tired of calling customer care. Can they fix the tower or terminate the contract because they clearly are in bridge.
