Insurance Refuted

I just had the worst experience ever. After paying my Vodacom insurance for years and years....when it was finally time to claim back, my claim was refuted. Insurance said the IME numbers that they have on file does not match. I bought my phone over a year ago, at Vodacom in the Nedbank building. Surely, they filled in the forms. Its not really my problem that Vodacom's own staff filled in the forms incorrectly. For future reference, I will never take out insurance with Vodacom again.
