Legal cover *** ****mers

Legal cover has representatives that stop them on the road sides that tells them lies... I was stopped at a shopping Centre and was told to swipe my card as shoprite was giving vouchers away so I was convinced and other people as well... Only to find out it was not vouchers getting given to people it was trying to get clients to take out covers and the cards get swiped for debit orders.. I lost money threw debit order which I didn't want cover and when calling the company they don't want to stop it and don't want to refund my money
