Load shedding signal

I have always been very happy with the signal from Vodacom, and never had issues with signal during load shedding. Unfortunately, that is no longer the case, literally 5 minutes after the power is cut, so is my signal, I have no signal, while everyone else in my household, who are with different service providers, have no such issues, for the duration of load shedding. I’ve had Sms’s about this, where they say they are aware of this issue, but is doing everything possible to limit the impact, but clearly they are not doing enough, 5 minutes of signal, and that’s it!!
