28 year Endowment policy no payout

METROPOLITAN LIFE YOU ARE BUNCH OF ******** THAT TAKE UNSUSPECTING PEOPLES MONEY FOR 28 YEARS AND THEN TELL THEM THEIR INVESTMENT IS IN THE NEGATIVE. My parents now retired took out an endowment policy with a guaranteed lump sum payout at maturity, only to find out at maturity that the policy has been in the negative for some time now. this begs to ask the question why were they not informed and why did you still deduct payments and taking already struggling peoples money. So for 28 years you took their money, saw that this was a dead end policy but you just kept on milking 2 working class, barely making ends meet people. YOU SHOULD BE ASHAMED OF YOURSELF!!! Why was their no broker or financial planner from metropolitan contacting them to advise them differently, surely this is your job because if we had the knowledge why would we need you. These 2 people having been saving their entire lives and was hoping for some relief in their old age but you are a bunch of ********. But even though you are sending us a bunch of information which a normal person will never understand to explain the is situation, we will still be making it known to all social media platforms and newspapers what a bunch of ******** you are.
