Launcher account hijacked, info changed, and acc was sold.

Hi there. So this morning I got several emails requesting to change an email address to one of my accounts on my launcher. I clicked the link that said if this wasn’t you, and changed my password. However I never got an email back regarding the account. I went to check the launcher and my account was logged out, tried to log in and it failed. I tried changing the password again with the same email on the launcher website, and it told me my account could not be found. I submitted a recovery report on RuneScape, just before doing so the person with my account sent in game screenshots to my personal email, as well as a receipt of sale. I have screenshots of everything and told them id be willing to send literally everything to prove I am the owner. How this iappened I have absolutely no idea. I did not have an auth, and I did not have backup codes so hopefully my 2k total account is not gone forever :,).

Just needed to vent. I submitted the report this morning and have yet to hear back yet and it stressing me tf out.

Cheers! Wish me luck.
