Insurance ripoff

I have been insured for over 2 years. My cellphone got damaged last week and i logged a claim. The insurance called and asked which number is insured. She asked for one number and i gave her. But i insured 2 cellphones numbers. And the second one is the one I was using when the damaged occured. I was never requested for it. My claim was rejected because i didn't provide the number. I don't understand how i can pay insurance and get rejected for a claim when the number is still in use and actually the one they are calling on. I'm livid because not once have i claimed from the insurance and when i do they reject my claim for a stupid reason with no substance.
