Yesterday my dad won the prizes then I try to send the message back using my email then haven't receive the prize even reply my message

It's a scam, you have won nothing. Do not give then any information.

Total scam. Tell him not to help a prince in Nigeria find his fortune as well. Rule of thumb, if you have to pay money to get a prize or money... it's a scam.

The internet lottery is a scam. They will ask for money as a fee to release the prize to you. You will pay the money and they will then ask for more for a different reason. They will keep asking and you will keep sending until you have nothing left and then they will not contact you anymore and you will have nothing except an empty bank account and many people saying "I told you so" and "how could you fall for that?"

I sincerely hope you haven't sent any bank account information.
