Vodacom Insurance with no service

I have been trying to cancel the Vodacom insurance on 3 of my devices since late May 2021. The consultant that sold my packages to me said just call *** from your phone. I called the line and got a reference number that the insurance on the 3 lines was cancelled. Then in September I called again and was assisted by Graisha Tsotetsi from Finrite ( at that stage) where she confirmed she resubmitted the cancelations and the credit for the insurance that was still running on the accounts. I have still not received my credit, two of the devices the insurance was cancelled and the 3rd is still running each month. I phoned the insurance line multiple times where they just cut the call after holding on for them to see what the problem is. I went to the Vodacom Shop in Meyersdal where their staff assisted me to get hold of the insurance company ( outsourced) They requested that we forward the email to them with the confirmation that it was cancelled. we did that the same day. Now they just want the same paperwork from the start and say that the cancellation was never done? However 2 devices was cancelled just not the 3rd? And the credit never paid out. They refuse to assist in the matter. This is now going on for almost a year. And no one will assist. I want Mr Shameel Joosub to resolve this as a matter of urgency or I will take it further.
