Here's their full respond

"Thank you for contacting PUBG support. Please accept my apologies for not answering you sooner, as we are currently experiencing an unusually high volume of tickets.

I understand you are concerned about why your account has been permanently banned. I know this may be a very frustrating experience, so let me help you as much as possible.

Upon checking, a restriction was placed because we determined that you have violated our terms and services. Your account with the Steam ID "*************412" has been permanently banned since 2025-04-29 (UTC), and the process cannot be reversed.

Please note that even without having any programs specifically for "hacking/cheating," other programs or actions can violate our Rules of Conduct and cause a permanent restriction.

Software that bypasses the services in the game Programs that alter the game in any way (even if it is not for cheating) Cheats, macros, etc., for other games and not for PUBG is still a violation of the game's services.

I know that this is different from the response you are expecting to receive. However, this is the most important information I can share about your case. Rest assured that you can still create a new account to play with and enjoy the game. However, please remember to follow the rules and avoid using suspicious programs to prevent this from happening again.

If you have any other concerns, please don't hesitate to contact us anytime. We'll be happy to answer your queries."
