Bad service or should i say no service

I switched to vuma had signal for first week only, i called them 3 days in a row bt nothing, their call centre operation is pathetic as u on the line for more then half an hour always being no3 in line, i have no signal and was advised team will come out in next 48 hours, im way pass the 48 hours still nothing, emailed managment aswell but also no reply, however come month end they the first to deduct for service not rendered.i regret signing up with them as they a waste of time
