Afrihost client zone misleading and expensive

I've had constant speed battles with afrihost as well as excessive data usage on the capped services and therefore bit the bullet and chose to go for a slower speed internet but an uncapped line, which I knew would end up driving me crazy with the shaping of the line which would have been out of my control. I was told to use clientzone to make my package change, which I did, and chose a uncapped 8mb package which should have costed about R670 a month (about 100 more then my capped 100 gig 10mb line). I now received an email stating that my pro rata for last month and the bill for this month is R1400+. I've never paid so much for Internet in my life. From what I've guessed I was changed the full rate for my old package as well as the full rate for my new package. Clientzone is misleading. If I had knows this was the hidden cost I would have cancelled my package instead of migrating to the uncapped package. When I heard of the mix up I called in to confirm and when I found it to be true I said I would be cancelling all services. <br> <br> I refuse to pay this. You can keep your internet
