Hi @Sashashep
I can imagine it's concerning when you've received an email saying that you've not paid your bill.
I'd recommend checking the sender's email address, just to make sure that the email is a genuine email from EE.
You can find more information on how to avoid scams on our How to avoid scams web page.
If the email is a genuine EE email, I'd recommend giving us a call, then a guide can get this looked into for you.
