The biggest question now is, on the one hand, does the insurance company have any definite evidence to prove that you are a pre-insurance disease or a congenital disease? On the other hand, do you have any evidence to prove that you informed the salesman when you insured, and the salesman clearly replied that it could be reimbursed? If the insurance company has the evidence and you don't, you may have to suffer a loss.
Many ordinary people mistakenly believe the lies of a few unscrupulous salesmen, but don't pay attention to written contracts such as insurance clauses. So many people have suffered in this respect. I hope that the general public will learn a lesson and be vigilant. When taking out insurance, they must pay attention to written evidence. If they can't find anything in the written contract, they must write it down and sign it to avoid being cheated.
