I sincerely hope you're kidding! If you actually gave your SSN & CC number to an unverified caller you are going to find out "what the heck is going on" in spades. Call your CC company immediately & cancel your card. Have a new one issued. Contact your bank & put alerts on your accts. Contact the CRAs & put alerts on all activity. You've been scammed & I pray (for your sake) that not too much damage has already been done.
You need to become an educated consumer. You're soon to understand why. Naivety is no longer an excuse.
Be Safe. Be Aware.

I'm with Gunnar. I HOPE you're trying to be funny, because if you aren't you're about to spend a LOT of time and energy trying to clean up the mess these scammer about going to make of your credit, your bank account, and any other information they can get their hands on.

In addition to what Gunnar suggested you do (which you should ABSOLUTELY follow TO THE LETTER) if might be wise to give your relatives a call and inform them that you've been majorly scammed, and there's a severe likelihood the scammers have their names, (and possibly numbers) as well.

Cancel your credit card immediately and report to police and freeze all your accounts.
They definitely are scam

I received a call from this number this morning. A male voice, claiming to be from the IRS said that I must call immediately because a law suit is getting filed today unless I pay  what is owed.  I reported this to the Atty. General's office. (He also claimed he had been trying to get in touch with me for weeks.) He had not! IRS contacts by mail...Not phone.

lucky me, this is my second call from these people today. As in the above messages- don't give anyone anything anytime.  The IRS sends information though the mail not over the phone.  Be alert and stay awake!!!
