According to your evidence, Fiverr can put a seller account under review. After 60 days, they may suspend it or allow the seller to keep using it. However, they cannot return the money you transferred. In such a case, you can simply visit your bank or connect with your local police if you are certain that you were scammed. If you're just thinking and not sure, there might not be any use in taking action. Alternatively, if the seller is busy, it might be best to wait for a day before initiating any action.
