Non existant Telkom network

My cellphone account is through Telkom. A couple of months ago, my coverage would sporadically drop with a message of no mobile network. When I manually look for networks, every one says "forbidden". As a result, I can not receive any calls or SMS. The occurrences of this error became longer and now it is permanent. After driving for 75kms and spending a horrific 2 hours in Telkom, George, yesterday, I got a SIM swap. Of course, I picked up coverage while I was in George. As soon as I was on my way home, exactly the same thing happened and I am still without service. Interestingly, the customers on either side of me in Telkom were there for exactly the same reasons, but nobody seems to understand this is not an isolated case, but rather a trend. My husband has sat on the phone to Telkom for an hour and they tell him 1. They have sent me an sms telling me how to reset something. I DON'T GET SMS!!! no network coverage... 2. I am told to put in a code, send it and then reboot. I cant do that as I don't have network coverage. 3. Now they tell my husband that they can't help him, I must call them. I CANT CALL!!!!
