Telkom....ADSL cancellation

Very disappointing. We have had ADSL for a couple of years (6-8 years) and never had a problem with sufficient Data. In Feb 2019 we realised that there was a problem with data and called them to find out the data was finished app the 22nd. In March the data was finished around the 9. I called again. Nobody could explain and we cancelled Telkom via the App as we were unable to do so telephonically. In April i popped in at Telkom store in Alberton who confirmed that it was cancelled and gave me a reference number. 1 may my acc was debited and I left it as I realised Data was loaded and thought this might have been the last one. They debited me again on 1 June for R303 which we returned as there was also no data. The 13th of June my account is debited with a double debit order, ie R607. I called Telkom. The consultant insisted the line is still active. I requested for a manager and was advised that they would call me back. Still waiting. I have again returned the debit order.
