Telkom is a disgrace!

Telkom closed their service for our adsl account in September 2019 because we did not upgrade to their latest service. They shut off their service for a land land and wifi with no prior warning. We closed the debit order at the bank for the amount of R659 yet Telkom have continued to draw down a payment of R659 every month from our bank account since September 2019, for no service rendered in spite of the fact that we have had something like 6 telephone calls, four visits to the Telkom outlets in Nicolway and Fourways to tell them they closed our account. STILL we are paying Telkom for a service that is not delivered. We sold our house in October and they are still billing us for a service to a house that is no longer in our name. Can anybody help us get our money back from Telkom. Their outlet service in nothing short of appalling. Staff sitting on their computers not helping the public. They are a disgrace!
