********** Contract Raised By Vodacom

I had an contract with Vodacom that I opened on my prepaid sim to get 1GB data about over 2 years ago. It has since passed it's period but I was still happy to let them debit my account for that data. This month I was amazed to find out that Vodacom charged my account for R684.60. I went to find out at Vodacom what on earth is going on, only to find out that a Flexi 120 contract for Samsung S8 was taken out on my name *****ently. I have never had a cellphone contract with Vodacom so I don't know how their systems was breached. Must have really poor systems in place. I have contacted *****s department 3 times asking for update on the progress of their investigations and they not responding at all. It has been 8 days and it's coming apparent to me that Vodacom's main purpose is getting sales regardless of the means. Please Vodacom just say something, a simple we are looking into it would be appreciated.
