Unauthorized debiting of money from my account

I have been in contact with Vodacom the whole of last week but it seems there's a communication problem between the agents and myself. I called Vodacom requesting that my method of payment be changed from debit order to cash payment but to my surprise the opposite was done. I paid paid two cash payments of +-R600, which after making the payment I called Vodacom to make sure that the money reflected and I was told that it reflects on their system and furthermore the method of payment was changed.

This morning I received an SMS from my bank stating that Vodacom has deducted money of my account. To me this is theft, simply because my account is fully paid and the payment method is debit so whatbi don't understand is why Vodacom debited money off my account.

To make things worse I have now been told that I have to wait 2 weeks to get my cash payment.

Kindly explain to me why I should wait two weeks to get what's rightfully mine. You made a ****up yet I have to pay the price.

As thought that is not enough but it seems your account billing is incorrect. I have been overcharged and all the agents keep on telling me different stories (please train your staff) as to the reasons of deviation.

If I had it my way I would walkaway and cut all ties with Vodacom, clearly you can't be trusted.
