Vodacom - Insurance

I had a phone which got damaged and saw on my Vodacom invoice that i paid comprehensive insurance. (Didnt know it untill i saw my invoice). So because of that i took my phone in to get fixed, because i pay insurance. The qoute came back saying i dont have insurance so i phoned ***. They asked me for my cell number and the lady told me this number is insuring a Mr. Nkosi or somebody else. The Vodacom shop then contacted them on my behalf and found out there was a problem somewhere but didnt elaborate. My quess.. i paid for someone else. But "Vodacom will refund me" for the months i paid insurance. This all happend in the beginning of April but i still havent heard a word back from Vodacom. And phone not fixed because phone not ensured. No refund yet as well. Eventhough i paid insurance since August last year according to the vodashop.... I phoned a couple of time.. they say its escalated. I emailed.. to find out the details about the escalation.. no reply. Its like they are just igoring me. I would like to get feedback on the months i paid insurance which i was never meant to be paying. And when will i get refunded.
