Cell C Billing issues, again

<p>I upgraded my Cell C contract effective February 2016, and requested that my C-Surance be adjusted to suit the new device that I received. After numerous issues including billing and activation, which was only (sort of) resolved after a previous Hello Peter complaint, I finally had the C-Surance active. Skip ahead a few months to October; I received a series of SMSs stating that my C-Surance had been cancelled, re-activated and then changed to a larger package (none of which I requested or authorized). I called the contact center and was told that everything was in order and had been sorted out. When I received my bill (which I had to ask Cell C to email me as they never send it) I noticed pro-rata charges and that my C-Surance was cancelled at some point earlier in the year (around March), without my permission. It then also became apparent that my C-Surance had in fact been adjusted to a package much higher than the value of my phone (which costs me more per month). So I have now had to pay for Cell C's mistake (the pro-rata fees) as well as an insurance package, more expensive than the one I asked for. I've contacted the call center several times, and keep getting put on hold and then cut off, and any emails I send are not responded to. What do I need to do to get the service I requested?</p>
