Pushy call centre agents and incorrect information

I was called by a call centre agent sometime in October regarding my data contract - his words were something along the line of I would now be getting more data per month for less. At no stage was I informed that my data contract was being migrated, upgraded to a top up as this is not what I wanted and would never have agreed.<br> At no stage was it mentioned that my existing contract of a dual sim would be cancelled and that the contract would become a top up contract. This is so typical of the Vodacom call centre agents being incredibly pushy and not providing all the information. I called a number of times in November ( the call centre) to find out why my dual sim was no longer working and at no stage did anyone inform me that my contract had changed. I was advised to go into a voda shop. To my horror I have since discovered that my entire data contract has been changed. I insist that someone senior contacts me regarding this, I want a copy of the voice recording and I want my contract changed back to the way it was- able to work on a dual sim. I will also be porting everything that we have with Vodacom to FNB- far better service!!! I am disgusted by this and will go to the Ombudman
