Vodacom transfers from contract to prepaid and they zero your balance

My number was on a contract which was just cancelled and the number was converted to prepaid. Vodacom then unceremoniously zero's out all the airtime and sms's and data. This is ridiculous as the contract will still be paid. I bought extra data as well and this was also cancelled.

So something that basically has been paid for has now been taken away, this is not right.

This is theft.

Please contact me on the phone number (in question) which is provided and not email as I now cannot access my emails as the data I had has been taken away.
