Delay, mistake or refusal to cancell the contract I was duped into.

Since my last review, Vodacom has still not cancelled the contract I was duped into. I got an sms response on 15 April 2021, stated that the query is still in progress. It confirmed receipt of the devices, stated that cancellation has been logged and feedback will be provided once complete by Mondo Team. To date no feedback was provided. I made a follow up at Vodacom Irene today 03 May 2021 only to discover that, the contract for my other phone 082...upgraded on the 25 Jan 2021 is now cancelled and it is on prepaid. The one which was supposed to have been cancelled 072...is not cancelled. Is this a mistake, incompetence or blatant refusal to cancel the cotract I was duped into or what? It is now 3 months and 3 days I am struggling with this problem. If this matter is not resolved in the next 7 days I have no choice but report the matter to the Consumer Commission.
