Hello @user_0a18ca ! The first place to check would be our Customer Security Assurance sites list of alerts here : https://internet-security-site-web.wc-g2.cf.comcast.net/help/alerts it is really useful! I would also recommend that when in doubt, reach out to us directly. The ways to contact us are listed on our site here: https://www.xfinity.com/support/contact-us  We can check your account to see if a call was or text was made from us. If you still need a hand, please send a direct message to us by clicking the chat icon in the upper right corner of the page, click on the pen and paper icon, then enter “Xfinity Support” in the “To” section. Please include your full name and complete street address. Thanks!
