I WANT MY MONEY BACK I DIDNT TAKE YOUR PLAN

I am not happy at all why is my money debited when I didn't take up the plan? One of your guys came in at my work place and told me about the funeral cover and I said to him I don't want to take the plan before I read the reviews and he said to me no Im gonna take your details down for statistics purposes i agreed then when he came to the banking details I said no I don't want my money debited and he said no no don't worry someone will have to call u first and continue with them over the phone so you can take up the cover if u decide to i was like okay Im supposed now when my money is debited and I can't reverse it because when he ask if I can do a debit check I said no and i declined it, I went to the bank they said no they can't refund it i should call The unlimited this morning i called then I was put on hold and after a good 12 min with my airtime I said to the lady I want my refund and to cancel this coz I didn't take it she said yes I will help you after talking she said no unfortunately if u have cancelled it I won't be able to refund u I asked why coz this is day light ******* I WANT NY MONEY then she had the audacity to hang up on me wow
