Yup, my money says dude did something very wrong (clicked in email link or shady ad would be my first guesses) and just gave someone their info. Quick whois search shows Getmypayment.com and .net are not owned or hosted by the US Government. One is a GoDaddy site, the other someone else (1&1 IONOS SE if you're really interested). The .com site has all owner info redacted for privacy, .net says to contact "Domains By Proxy" for info (no, that doesn't sound suspicious
)
Sorry buddy, always check those links and their sources before clicking.
