could you maybe reply with an image of the message you're looking at? (without revealing any personal information, if you do (like address, email (maybe), etc) it will probably be deleted unless a mod could edit the image but i don't think they can or will do that) because honestly to me this just sounds like a big scam but i'm not going to jump to conclusions, and if you want the answer to the email stuff, if its an outlook email, you can go to https://outlook.live.com/, if its gmail you can go to https://mail.google.com/, if its yahoo you can go to https://www.yahoo.com/ (i would give you the link that would take you to your mail section for yahoo but i'm not logged into my yahoo account right now so i don't know the url), etc, i would include more links but i don't have any other email account services like aol and stuff, so whatever email provider is, go to the main online mail page and then you will want to somehow get to your account info (where it says the full email address, username, password, stuff like that) and reset your password (this is the more complicated way btw, if you know another way to reset your email's password then that'll definitely work the same), again, i wouldn't be too stressed unless you know its official because honestly even i get this stuff, i was actually going to send an example that would've been on the account that i share with a few friends that is filled with spam but i forgot one of the people on the account got bored and cleared out all the spam and scam stuff so i wasn't able to find any examples but just trust me, stuff like this is common, if its an email, just make sure its official and if so or you just simply know its hacked then just reset the password to the hacked account, if you have any other questions, comments, or anything, feel free to ask more and i or someone else would love to help further (and again, if possible, you should include a screenshot of the message maybe, if possible)
