What to do if your parents were mis-sold insurance?

From https://www.straitstimes.com/business/admin-exe.... Like the article, 4 years ago, my mom and I went to UOB to renew FD and was sold the PruSave Max Limited Pay. Paid 60k (12k premiums for 5 years) on the spot of signing the insurance. The agent told us that it is better than FD and at maturity 75y.o or death, she would receive 80k.

However, recently i reviewed the contract and realised that only 43k is guaranteed while the remaining 37k is not. My mom and I were unaware of this before but the contract did state so.Even SSB gives better returns
