Poor, Poor Poor service

I have contacted Mweb twice about my left-over data that does not carry over to the next month on my data contract I have with them. Twice I was promised that the problem will be resolved and that I will be notified as soon as it happens. EMPTY PROMISES. But they do expect you to make use of their services even if they struggle to deliver a proper service. Can someone at Mweb that actually cares about the customers please contact me in order to resolve this issue.
