Max Life Insurance — Regarding my policy no[protected]

According to the policy I have signed up for 6 pay and the policy term is 6 years ...accordingly I have paid up for the entire 6 pay ...I have opted to take the guaranteed maturity sum assured in lumpsum on the maturity date of 18th November 2020 instead of the monthly payout...the executives at the Maxlife salt Lake kolkata did not guide me properly to claim the maturity lump sum .. I was told I can only take the surrender value and not the Guaranteed Maturity Sum assured spelt out under the policy on the maturity date 18th November 2020 ...
To be honest I am losing faith on maxlife after this incident ...
