please help me fast

hello I paid an Indian programmer to help me integrate the ads in my game and now he sent me a message that if I do not send him another 15 euros he will give me a strike on the game I posted on the play store because has a copy of the game is this possible?

Why wouldn’t it be possible? If you can download and install a game you can write a review for it. Below is a link for reporting reviews to Google. If he carries through with the threat submit a report with the full information.

Did you signed the contract, before sending money and project?

I made the payment on the fiverr there I found it please what could I do to protect my game:(

Like I already mentioned you can report them if they make a negative review. Additionally you can report them to Fiverr.
