oh yes it happend to me too.. about 7 yrs ago, some how they got all my info
and I don't really watch my bank account that much, (everything is autodraft) so when a $1400 bill arrived from "SPRINT" for 6 cell phones, and I do not even own a cell phone, I knew I was in trouble, fortunately my San Diego bank was way cool, they took care of the whole thing and got it all back, including the 20 or so porn sites that they signed me up for.
the lesson I learned is SHREAD EVERTHING!!!!!!!! then burn it, also call all the credit agencies, equafax, trans union and experian and lock your accounts with a password, none of the three will issue credit to anyone for any reason with out that password.
and so far so good!!!!! even I have to jump through hoops to use my credit now.
