No internet at all during load shedding with MTN, other networks work.

Very disappointing that during load shedding MTN has no internet access at all as compared to other providers. I have to switch over to Telkom in order to get internet access. The internet speed is not even slow, there is just reception but no internet at all. I have tried different routers, switching from 4G to 3G etc, nothing works, yet other networks still have internet access.
