I received 6 calls today alone from this number. 3 voice mails and 3 calls which were all automated telling me the IRS was filing lawsuit against me and to call back the number that called them. Problem that you have is I accidentally dialed the number back later when I was trying to call someone and it says the number has been disconnected or no longer in use.. But I knew it was a SCAM the minute they went over the 3rd call. I was a Manager in a Major Phone Carrier Call Center and know that the FCC does not allow more than 3 calls within a 24 hour time frame and thats ONLY if you have not spoken to the customer. Once the line is answered they are no longer allowed to call you again for another 24 hours from that time mark. (just a note for anyone in the future).
