False marketing

On or around the 23 June 2017. I made online application for an upgrade of my cellphone. I was on a top up package. The upgrade online was made for a Samsung Galaxy S8 with insurance similar to my existing package. Without completing any paperwork The prepaid package was converted in a contract without my consent. I've contacted Vodacom on several occasions regarding this issue, to no avail. Over and above requesting a reversal of the contract I have been informed that I have multiple subscriptions and no insurance for the device. I did do an early upgrade but am being billed for 2 devices, duplicated sundries etc. Vodacom online has never responded to any calls or emails. Why can't they honour the package sold online and cancel the unauthorized subscriptions. Please help From a bill of R650pm. I have an account of over R4000.00.

Many Thanks S.Sookraj ********** 659 ********** Vodacom ACC. No ********** 378
