Correct his birth date

I added my wide to my policy in 2005.I send them his I'd copy and all the years his date of birth was admitted and it was correct.last week they send me correspondence with his age being 47 and he is born 1959.in 2005 they admitted him because I send them a copy of his I'd. My worry is today they say his age is 47.so can you imagine if he can pass on the run around I will be doing for them to pay me out.plse check your records and give me his real age and not the 47 you ae telling me about
