VODACOM ***** CONSUMER'S MONEY

I cancelled my ****le data contract with Vodacom twice, got reference numbers but the debit order still goes through. I hold on the line for at least 15 minutes before getting through to a consultant (considering that's the only contract I have with Vodacom it costs me money to hold) who after doing whatever they do twice says they've cancelled the contract, yet I still get debited. They are a bunch of *********** people, when I got that contract it was done over the phone within minutes and they called me. When I want to cancel it's hours and still nothing gets done. After cancelling on 12/11/18 and 16/01/19 (spoke to Kingsley Mokgabugi), I phoned again on 29/01/19 (spoke to Bongani) and asked to speak to a manager who wasn't available and I refused to hold so asked that the manager/team leader (Maria) calls me back but think that was wishful thinking on my behalf and I was expecting too much from such a lousy company. If I didn't pay my account they would take legal actions against me but when they take my money for services that I'm not using and have specifically cancelled then it's ok. At the end of the day it's theft!!!! What happened to consumer's act???? It's almost like they make it impossible to cancel any contract and "best" is cancellation cannot be done in store, only via call centre. I am totally disgusted in Vodacom and will NEVER EVER use their services again! Am I going to be refunded the 2 months that I was debited and haven't used the data????? My only way out is to put a block against the debit order!
