Trouble with Experian

I was online checking my Experian credit info and noticed two duplicate street addresses but one of each had a wrong apt number. So, I disputed both saying I never lived there. An hour later I received an email from Experian saying my dispute is completed When I went online to sign into my Experian account I found one dispute showed a PO Box in El Paso as deleted. The other dispute showed an “updated” address in San Jose . Both cities I ‘ve never lived in.

Is this a mistake by Experian or Identity theft and someone found a way into my Experian account?

Experian is close to impossible to reach by phone
