How to reach Comcast legal dept

I need to reach Comcast/Xfinity Legal Dept.  I've submitted Fraud Packets 3 times, and a Legal Dispute over a Fraudulent account, moved to my name and bank account !  As I'm sure everyone knows, you can never get the same person on the phone, but there was a person about 10 days ago, in their legal dept, that told me he had figured it out: that an employee had cut n pasted my information onto someone else's account!!  He was going to speak to his manager and call me back in 10 min, but of course, did not, and I can't even get a phone # to his dept.  I have managed to turn off auto pay, but now Xfinity is telling me, it could take up to 120 days for these past due charges  to come off my credit report, which is MY BUSINESS CHECKING ACCOUNT !!!

This is absurd, and i will go to great lengths to be sure many many people hear about this!
