CONTRACT CANCELATION

On the 18 of February. I made an online purchase of A12 Samsung phone and it stated a consultant will call you back to complete the process. A lady from durban vodacom contacted me, I told her that I wanted the A12 Samsung on u flexi top up of 125rand only. She went and put me on a wrong package of sim only top up of 125.which I did not request,I have been calling vodacom to get this contract cancelled,so I can purchase the phone,they told me it takes 24 to 72 hours which it has already passes. Im angry at the lady that completed my online purchase,she failed to listen to my request.My debit date is on 25 this has to be sorted before that. Disappointed by the service.
