FUNERAL DIGNITY PLAN

On the 7th April 2015, I took out funeral cover, included both my parents and daughter, which clientele did contact my parents to confirm everything with my parents including the date of birth and if they are aware of this plan, to my surprise on the 20 April 2016, decided to take up another police with them and add my mother as beneficiary, only to find out on the documentation that My mother date of birth is 16/04/1963 where my Mother was born 14/04/1953 and My dad date of birth is 07/07/1948 while my dad was born on 15/07/1938 both the decade difference, when I call clientele to rectify this, they said my premium would double to accommodate this changes, I requested to cancel all my polices with them, they said I will forfeit all my paid premiums and they'll still debit my account this month, which I don't understand even if whoever created my policy missed on my parents date, how possible that they'll miss it twice by the time they confirmed with both my parents. and why would they still bill me for this month since even if god forbid something happen to one of my additional members the policy won't pay out since the date are incorrect.
