Bought insurance from Vodacom but it is not activated

I called Vodacom on 13 Dec 2024, to activate insurance on my new device I had upgraded with them, documents were sent to me to be completed, signed and sent back to them, which I did. I was also told activation was effective immediately. Since Tuesday I have been inundated with calls from Vodacom insurance asking me to take out cover on my new device, me having to explain to them I have already taken out insurance, but they have nothing on there system. It is completely annoying, as I as the customer called and was told my insurance is activated. Where are there calls that are kept for record purposes,because had my device been damaged or ****** in the past few days,I would not have been covered. I then get demeaned by the consultants as if I do not understand the difference between insurance on the device and contract cover. I even have the name of the consultant who sent me an email and told me my device was activated on Friday 13 Dec 2024. I do not understand if Vodacom makes more money by calling individuals to activate insurance instead of us activating it on our own. I am completely annoyed with the service from Vodacom after I have been a customer for over 20 years.
