UNAUTHORIZED DEBITING MY ABSA A/C

We switched from Vodacom to Telkom in Jan. 2019, retaining our old numbers, and in the process CANCELLED two contracts at Vodacom. Trying for months to contact Vodacom on ********** and ********** because, UNAUTHORIZED, they keep debiting my ABSA Current a/c which transaction I then go and reverse at my ABSA branch. This morning I reversed R1,346-73. Local Vodashop tells me Vodacom have created two GHOST NUMBERS in my name, replacing the two numbers previously CANCELLED. They now charge me for these GHOST NUMBERS which I NEVER EVER authorized them to do. It is useless trying to call Vodacom BILLING and/or CANCELLATIONS numbers! Calls are simply "ended"! So, does Vodacom have carteblanche accessing accounts and debiting these willy-nilly? This MUST be *******!
