Still trying to exercise cool-off after three months of being sent from pillar to post

I posted previously on 10 Oct about the same issue: https://www.hellopeter.com/vodacom/reviews/impossible-to-exercise-right-to-cool-off-***

Dear Vodacom Consumer Website Team I ask for your assistance again, as no other means of contact results in any action from Vodacom. I have been trying to get this issue fixed for 88 days and have spoken to 9 people at Vodacom. My problem has not been resolved. I was contacted after my previous HelloPeter post, and things happened, but were not completed. I am now slightly worse off than before. I was contacted on the 13th of Oct (I think - this time I didn't save all my call records) and the person kind of again tried to sell the bad deal to me, basically explaining that it would be difficult to undo it now. I declined and asked that the upgrades be stopped. He said he will have to do some sort of reversal - cumbersome but possible. On the 18th of Oct a courier came and collected the three (unopened) routers that were part of the deals. I received SMSes confirming that they were successfully returned on 20 Oct. (The fourth unwanted upgrade didn't have a router, but was also part of my cool-off request.) This seemed very encouraging and I hoped that would be the end of it. But 1 Nov came and went as did 1 Dec. My Vodacom app says that I still have (and pay for) the four unwanted bloated contracts that only expire in Sep 2024 - except I now also don't have my free routers anymore, because that part of the reversal was successful. PLEASE SORT THIS OUT ASAP - i.e. restore my contracts to what they were on 1 Sep 2022. (I can live with paying the extra fees for the past three months, but not with being tied to this for two years!)
