I've got a call from someone who said that I got selected into commercial models and the location is at Camden studios but I made a payment deposit to Thomas street studios, Manchester. I went for photo shoot yesterday and everything went well. Finally when I met someone there who told me that modeling jobs are too good. Some people like me got successful and they are earning 2000 pounds per day. He suggested me to choose better package so I chose 1500 pounds silver package for agent, digital z card, portfolio website and pictures. I told I'll pay monthly installments. I've already paid 100 pounds including deposit. My 400 pounds will be deducted from my account on 22nd of this month. From next month onwards 100 pounds will be deducted for 11 months. I signed the contract without thinking twice. After coming home, I researched about this and it says it's a scam. They have my bank details too. If I block my card before they deduct my money, they can take me to court if I don't pay. What should I do? I've already signed the contract. They gave me another copy of contract but there's no sign of it. They have the contract which I signed but the one which I have, it doesn't have my signature. They can threaten me or put a blame on me for signing the contract. What should I do? Can I ask bank to block my card and ignore?
