Extremely unsatisfied with Telkom

Opted for upgrade and the consultant opened a new account instead. They have been debiting my account with R4000 to R5000 for 3 months now for a new contract I never wanted. Impossible to resolve this issue. I have been emailing and calling with no one assisting with my account issue . Telkom even suspended my account. Have not been able to use my phone for the second month now.
