Cell C constant no service, then getting poor support from them

The last two weeks or so I have had very little to NO service signal at all from Cell C at work, (gps coordinates -26.089652, 28.470324 ). I have logged network issues, then I get asked if I know if there are load shedding in this area, and I'm also being told that BTW, they have given me 1Gb free data.

I have already lost business, orders that should have been delivered here was sent back due to courier companies that cannot get hold of me. Me wife's car broke down, it took her more than an hour to get hold of me due to the fact that here is no service, the mechanic that is repairing her car can't get hold of me, other stuff that I need to do on the net I cannot do because here is no service.

Cell C just simply say that the issue MIGHT be due to load shedding (a fact that I'm suppose to know where and when load shedding should take place according to them), I was also told to just connect to Vodacom or MTN and roam on that network when Cell C is down, but every time I try, my sim card say that it is not allowed. What the hell must I do with 1Gb free data if I cannot connect to their network. I am up in arms. I have tried to phone their head office, but the number given for the head office belongs to Discovery Bank.

Their support is really really bad. Will definitely be cancelling my other contracts when they expire
