Upgrade not requested ***

I was due for and upgrade around September last year 2018, but chose not to due to the packages offered and how expensive they are, however on Friday i decided to cancel my contract with Vodacom but somehow got through to the retensions and spoke to a guys called Sive, he assisted me in offering me data and extra minutes etc etc, to which i was excited and thought that he is actually helping me, taking into account that i have been with Vodacom for over 22 years, to my surprise yesterday i visited a vodacom store in mall of the south and just enquired on when i could upgrade my contract (just out of curiousity) only to be told that i actually upgraded on Friday, .....at no point in my discussion did i advise that i wanted to upgrade, and at no point did he advise that he was upgrading me.....that too on a SIM only upgrade.......why would i do that when my phone is almost 4 years old.....i could have rather then upgraded for a new phone....i logged a complaint this morning again and he called me back argueing that i insisted on an upgrade.....my calls are recorded and so are theres, i played back my recording in the car before calling them and reassured myself that no mention of an upgrade was ever made (both ways) i have asked that his manager call me and till now nothing.......i am really really upset again with Vodacom, and since i still have up to 7 days to cancel.....they are not giving me this option....i will now take to social media as well as the consumer council of this matter is not resolved today.
