Over billed by 10k

<p>I was incorrectly billed due to a technical issue with how the app on an apple computer reads data. The modem was plugged in but not connected in the app and it read my adsl data as 3g data. Im now sitting with a bill of over R10k. No one will hear me out. They just say the bill is correct. The contract was actually cancelled in June but was billed up untill January this year. Poor resolution. I'm cancelling all my vodacom contracts and I'm getting everyone I know to move away from Vodacom. Really unhappy with the way this case is being handles by vodacom. It is almost impossable to get through to the call centre and the people who are supposed to help you are not helpfull at all. </p>
