Xfinity internet is hacked and I can't even monitor my home wifi

Xfinity has the absolute worst customer support although I personally believe that American internet companies are competing for that award. I can't access the Xfinity admin tool anymore (after wasting several hours on customer support chat feature trying to get help from third-world support agents in Mumbai who couldn't do squat) and I can't view my home network to see who all is hacking into my internet. I know for a fact that my next door neighbors are hacking me, but I can't get into my home network account to take screen shots. Xfinity is over-ripe for a class action for leaking personal information and personal accounts. I'm already receiving a settlement from AT&T Inc. Customer Data Security Breach Litigation, MDL Docket No. 3:24-md-03114-E in a class action for leaking my personal email account to a hacker in January 2024. These companies are not bright. By screwing their customers, they always wind up screwing themselves. I want to be able to access the admin tool and my home network account and I can do neither.
