Vodacom debit my account for a *****

In January vodacom debited my account R266 from my bank and i was suprised and i went to vodacom to inquire about this money and i was told that is for a new contract of iphone X and samsung note 8 so i told the cunsultant that i never took any of this phone and he told me i must bring affidavit and id so i did so he even gave me ref: EC-1JSE-2XQA1B told me vodacom will give feedback after 7-14 days. So i left and 14days pass no feedback from vodacom and so i went back to vodacom and in February they debited R2996.95 so i went back to vodacomshop and the same consultant who helped me before he called vodacom to find out whats going on and they spoke to me from legal and ensured me that vodacom will contact me and they even gave me ***** number which i called but they was no answer. So the consultant from vodacom even did other service requests with ref:1- ********** ********** on the 28 february. So i want to know whts going on and why they are not giving me and feedback and they must refund me my money becouse i dont know this two contract i only have one contract. So the consultant from the store was very helpful but i am very disappointed with vodacom for not responding and keep debitting ***** account.
