worst service

firstly when you call their contact center the background is horrible, they make you hold for nothing, first thing in the morning my subscription said I have to pay R469 there was a reversal of R419 which they failed to check where was it coming from I spoke to Sipho I explained to me him that I'm on my cellphone he said hell phone me back he never phones me back I phoned again there was a lady who just put me on mute, how can they not see the reversal since is on their side? I think they don't know their job or don't have answers.
