Loadshedding

I farm next to the N18 in North West, between Stella and Mahikeng. Loadshedding is a reality, BUT surely Vodacom's service should not be affected by this. One would assume that a tower would have some kind of power backup. As soon as there is loadshedding, our whole area has no service. This is a huge problem seeing that communication can sometimes be a life and death issue in rural communities.
