Marquis Chapman ( burial)

My son Marquis was an epileptic patient. He had life insurance for 12 until I found out that his birth year was put in in correctly. I called and informed insurance company that his year was in correct, they informed me to send his birth certificate and they will correct it. Well they cancelled his policy. I found a new company and they are saying it’s too soon for them to pay. I need help giving my son a proper burial . Any help will be greatly appreciated. I’m torn to pieces to know that having insurance for that long that they would leave me without anything to bury my child.
