Notification of new contract application

On the 28th/02/2016 I went to Vodacom 4U. Shop 128. at Maponya Mall to apply for a new contract phone, Bongane assisted me and he told me the contract has been approved but I will be required to pay R600 once off fee due to my credit rating. As I was to pay the required money, Bongane told me he activated the wrong deal a 16G instead of a 32G he then ntold me it will take approxamatately 24hours to cancel the wrong deal and get the correct one activated (which hasnt happend). I then called the store on the 2nd/03/2016 Tuesday, and then Bongane told me they still busy processing the deal he will call me back but never did, I then called in again on the 03rd/03/2016 just to do a follow up but was advised that he Bongane is shift off, but the person who answered the phone didnt even bother to assist me. On the 04th/03/2016 I called in again and was told Bongane is on training, again the lady who answered never bothered to do a follow up for me and advise on the progress instead she said she will get Bongane to call me back which didn't happen, now when i checked my account on the internet banking i discovered that Vodacom has deducted an amount of R296.00 for something I don't have.
