Vodacom and Vodacom Insurance

Good day Last year in April i upgraded my cell phone contract with insurance. Last week my phone broke and i took it in for repairs. The past weekend i was contacted saying that i do not have insurance. I finally got hold of someone from Vodacom and he is telling me that i did fill out and submit the insurance papers but there was a system error so it did not go through. So where does this leave me as i was under the impression that i have insurance and now my phone is at repairs and apparently do not have insurance because the person who submitted my insurance papers failed to resubmit them. I have been on the phone with Vodacom from last week trying to resolve this and my call keeps getting disconnected. I even called the store where i upgraded and they are saying i have to call customer care. i dont know what to do??????
