360 Play review: games

Taking money from my bank account. I wish to cancel this direct debit and any communication. I feel this was a scam to get involved in gambling, i'm not a gambler. The offer they made on their website was to pay £1 and I would receive an apple I phone, but never mentioned any about gambling or games. This offer was shown on their website, and they offered me this iphone 11 if paid them £1, the next thing I knew they had taken £ 49.50 from my bank account without any warning what this was for.
I would like my money refunded and don't want any more money taken from my bank account
