Un satisfy telkom client

I struggle with telkom mobile. Telkom suspend my lines since the 11th of August before the debit order the 15th of August. According to telkom I am in arears. According to my debit orders I am up to date. I struggle for more than a week to speak to a agent. I mannage to speak to somebody and according to the agent I am up to date it is a tecnical fault on their side. As from the 25th of August they promise to fix the problem and it will take 24 to 72 to fix. On the 28 of August at 19h00 a agent call me to say they call from a debt collecters because I ow telkom R3600 for payment not reciecve. I am very very dissapointed in the service that I receive from telkom. What about my airtime and data that I couldn't use in all this time that I did pay.
