Horrible Service

Mweb has dropped the ball tremendously, I have spent over R300 on airtime just to get them to restore my connection. Even now I am without internet because after being on hold for a very long time the agent who is supposed to help, hangs the call. On the 16th of December I called in and I enquired that if I made a payment on that day will it carry over to the 16th if January and two of the agents confirmed that it will but surprisingly on the first of January my internet was suspended so till today there is no help or communication from their side. Anyone who knows please help, because it is a month to month if I source another provider now will they help me or I should cancel first with Mweb then wait ( which I know will be a hassle to get them to cancel as I have seen other reviews regarding that) or what should I do because I need internet.
