Funeral cover "reimburse rights"

I open my funeral cover with old mutual 3 years back,I have been paying R580 all these years i was fine with it,I was at the branch last week to find some info about my funeral cover when i ask the lady why i am paying a lot of money for this she told me the people that i cover they are duplicated so i have been paying double for them the lady said the is nothing she can do then she cancelled the duplicated policy, I want to know what haapened to the money i have been paying ,m so angry i even thinking to cancel everything and close my money account. I feel like old mutual must repay me back my money that's a lot of money that i lost.
