This man was going to help me get back some money from scam, he promised to pay me back toda yesterday and the day before that, but he started to ask for more and more fees, I even had to ask my sister to help me and she paid 800 euro in total. He has used 2 walletadresses wich I sent to. From the date 22 februari-23. After the last sending this morning and he was supposed to send the bitcoin, he called and told me that I had to pay 550 euro more fir autorisationfee whatever that is. I asked him to pay everything back but he say he can because the funds are locked in the wallet. I want him to send back everything to me. But he refuse. Can you assisist on this. I guess this upfront fees are scams.
