Poor service

My sister has had no connection since the mid of Nov and has been calling and not getting no solution except for reference numbers which have no resolution, she paid a full month subscription still no connection. Such a poor service no communication. Her account is set up under my name and that was done by lazy employees we ddnt mind at the time but now its a problem as they cant pickup her acc using her ID she needs to use mine. Somehow they make it our fault that lazu people couldnt do their work properly. Plz give our money back if u cant provide service.
