Rain service non existent

I literally live 300m metres from a tower but cN. Or get signal Like really I pay almost R500 a mo tj for what for no service. And when I want to talk to a consultant guess what there is nobody to talk to. What service are they offering if we can't talk to someone when we experience problem. Guys think 20 times before you decide to take a data package from these guys. They take your mo WY and give you nothing.
