Payment for an insurance policy

I purchased a 10 year paid up Insurance policy 3/6/1986.The agent sold the policy stating that it would be paid up in 10 yrs.State Farm miscalculated the bond returns and told people they had to make up the difference.A class action suit was filed and State Farm lost so for the past years they made up the difference.Now after 22 years the agent is stating I have to pay $142.20 tokeep the policy active.If the policy was paid up in 10 years according to their actuaries,why do policy holders have to continue paying the policy?Thank, Eugene Trautner 610 436-4526
