Complete scam. I called them back and told them to get a real job, they disconnected the call, and when I called back the number is no longer in service.
Two messages in one day to call them ASAP! IRS is filling suit. Same as above posts. Did not call them back. Googled the number first. Just as I thought. Went through this last year too!
Electronic call telling me to contact the IRS immediately @ 305-224-17396. Yes I wrote those last five digits correctly. Hopefully the IRS will shut these people down, hard to tell what their scam is.
