Upgrade Issue since February 2018

I refer to a previous reference 1- ********** ********** which I thought had been resolved on the 11 June 2018. I thanked the customer services manager Rudi-Jo Stephan Le Roux and praised Vodacom for eventually resolving my issue. To my horror I received my July account, only to find I had yet again been charged for a handset which I do not have as I upgraded without a handset!!!! I logged a new call on the 31st July and to date I have had no resolve. Please could someone assist in resolving this issue once and for all!!!!!!!!!!!!!!!!!!!!
