Vodacom aftersale cancellation

In December last year I took out a contract with Vodacom for my father and everything was fine. Then the 19th of April they phoned me and sold me a migration package on that contract. After speaking with my dad about it we realised it was not neseccary, the original contract was fine. So as from the 11th of May 2023 I have been trying to get that migration package cancelled but everytime I just get told that it has been escalates but it never gets cancelled. Unfortunately I did not take down thebpersons name I spoke to that day but I again tried the Monday, Tuesday and Wednesday to phone just to get told they are ecpexting technical difficulties. Eventually I got assitance from a lady called Jody on the 18th of May that said she will escalate I can phone again the 20th. So I did and spoke to a lady by the name of Kayanda who again said it will be escalated. Then again I phoned on the 22nd of May, soke to Patricia who just said the same thing again. So today the 24th I phoned again, spoke to Nonhlanla who said it will yet again be escalated and I must phone backnin 3 days. How can it take this long to cancel something that took 5 minutes to activate. And the stores don't assist you either as they just say because it was done telephonically you must phone the call centre.
