Device contract *******ly added to my account!

You have a bunch of ********* working for you!! One of your sales consultants *******ly activated a device contract on my account when I upgraded a Data bundle contract in February 2018, I only discovered this when I went in to a Telkom branch today to apply for a device contract to be added to my data bundle contract. I specifically recall declining the offer that this person made, and he acknowledged me as well. I need someone to investigate and listen to the call and then cancel this contract so that I can get the device contract that I wanted to get. I was also planning to transfer my Cell C contract to Telkom seeing that it expires in two months, but if this is the type of service I can expect, I'm not so sure?? The contract in question is the one listed below in the Reference number field
