VodaCom insurance bad and worse service

I am so disappointed on Vodacom, i have been a loyal and contracted member for over 20 years. I recently lost a cellphone which is insured by Vodacom insurance to date and when i submitted a claim it was declined their reason which doesn’t make sense is that the cellphone when was lost was not linked to any of my Vodacom numbers and they admitted when they insuring the cellphone Vodacom didn’t link to any of my numbers which is strange and this is from one of contact i have with them and they have my contact numbers. I have to keep on calling and following up on the progress after i have submitted the claim as there was no communication, which is a very bad service for such a huge mobile provider very disappointing.
