I ignored the call, but it threatened legal action

When I called the number it said it was the IRS almost sounded convincing till they asked me to leave my name number and social security number.   REALLY  They have called my home everyday for a month.  They can find you but you can not find them. Gotta love technology.

They are in India or Pakistan.

I received a call from them also.  This is a scam that has been reported on all the major news channels.  The IRS will never call you on the phone they like to send nasty form letters.  I have my own bookkeeping and tax service and I can guarantee the IRS does not call you on the phone.  I blocked the number but will probably do no good because there is software that allows scammers to use fraudulent phone numbers.  Just another way for third world countries to obtain our personal information.

They identified themselves as the I R S hotline ...is there no penalty for false representation...:(
