Not proffesional

Last month i changed my banking details and my debit order date. The person i spoke with never bothered to explain that i would be double debited which resulted in the debit order being reversed. Now because vodacom does not train their people properly i have not got a mark on my account and i was charged R60 for the reversed debit order. I called vodacom to sort this out and i was given a reference and promised to be called back its now been exactly a week. Vodacom has untrained staff and no longer cares for their clients from what i have experienced. I had 6 contract, ive cancelled 1 and the rest will also soon be cancelled. I need service for my money.
