No One Available to Help Us Resolve

My husband and I got held up together with all the patients at the Drs Rooms in Florida in Feb 2020 and they took his phone. He has a limit on his phone and had to rush back to work. In the week he called to stop his phone number with Telkom and gave the case number of the *******. the end of Feb he received a bill for over R10 000 and on itemised billing was SMS's. To date the account is suspended and we cannot resolve. We tried to go to the Clearwater Mall store, they advised we must phone, We have reference numbers and reference numbers. We tried to call to make arrangements to pay it off and still they referred us to the online chat which doesnt work as the contact centre agent advised we should be able to resolve. To no avail and we still being billed monthly and the amount is growing whilst Telkom attempts to debit our account every month which is also costing us. There is just no recourse
