Horrible service

I was ****med by a Vodacom Rewards team member on 31 Oct 23, after telling him that I dont want any upgrade from him, he still went on and did an upgrade without my consent. I immediatly called vodacom to cancel the upgrade. I was told that it will be escalated and cancelled in 24-72 hours. Since then I weent to a store and called twice more to get it cancelled. Every consultant telling me it will take 24-72 hours. As to today it is still not cancelled. How can I be ****med by vodacom in 5 mins but it take weeks of begging to get it sorted out
