I had an entire Comcast account registered to someone with the same name in another part of the state that took me years to get rid of. Could even login with my email address because he registered it to my account and somehow the email side stepped verification.

Imagine dealing with Comcast customer support. Then imagine not even being a customer anymore trying to get this resolved. Now imagine explaining how you're not the person on the account yet have the same name and how this is a huge privacy/security violation.

Took years to get rid of. One day I'm waiting for a silly collections bill or something to show up in "my" name for the other person.
