My apple account got hacked, what do i do?

I downloaded the app called find my iPhone and when i logged into it, it had this random persons devise listed on it, there's only one way someone's devise could show up on it and thats if they have my apple ID for a few months i wasn't to worried about it until yesterday a new devise appeared on it it said it was my iPad, i don't even have an iPad, so thats when i started flippen out, so i went to try to switch my password and everything and it was asking me to fill out the security questions, but the security questions where not set up by me and i've never seen them before, at he bottom it told me if i did not remember it then it would send them to this email that started with the letterrm and i have no clue who that is, so as you can see i'm having a major problem with my apple ID being hacked, but thats not the worst part, i have my debit card info in there and i can't take it off, so yes i'm mad and i need help, anything would help, please and thank you.

There have been FALSE messages going out about hacked Apple accounts. I don't even have an Apple account and I got one! So check and make sure. If someone is using your account write a letter of protest to Apple and insist they remove your account. It is easier to reopen an account and scrap the old one with all of it's problems. Then file a complaint with the FCC; http://www.fcc.gov/complaints and an internet transaction complaint here; https://www.ftccomplaintassistant.gov/
