Who called from 3474801721

I filed a complaint with the FCC. Not sure if it will help since they seem to be calling from temporary phone numbers. Got one from a Virginia number and 2 from NY all today.

Left a message that claimed I am part of a law suit. Requested a call back.

Got this call on 4/1/2015, 3 times.  Message was inaudible at first then went into the same message about law suit being filed in local county court house and call our number right away.  I thought it stated IRS Dimetro.

Got the same call and messages 3 times yesterday. On the last call I answered the phone  and told them to mail me the summons and to stop calling.  Obviously I didn't give my address and they haven't called back.

yup.  Foreign accent.  Took me a while to understand "IRS"  I said the IRS doesn't make phone calls and he said "OK, I will send you a letter."
