Telkom Cancelled my contract without permission

This is absurd. My telkom contract was cancelled without my permission and the account is paid in full and has never been in arrears.<br> <br> After calling the call centre they told me that it was a pay as you go number and that it has been cancelled. This is now 36 hours later and nobody has came back to me. This was never a pay as you go number and is on contract<br> <br> I cannot receive or make calls, no internet, nothing. This is a business phone used for my tourism company and I am losing money. Who gives telkom the right to cancel my contract without any notification.
