Customer service

Good day , for the past few weeks I have been trying to get hold of Telkom however this seems almost impossible if you don't have a Telkom line to call the customer care line. Since the new upgrade for the Telkom app, it seems as though my night suffer is included into the balance reflecting on the app. My data has never experienced a complete used up ever since the opening of the account and the connected device wifi usage doesn't reconcile with the app balances. I have attempted to get in contact via facebook & twitter however seems to be going in circles....
