Left voice mail saying IRS was filing a lawsuit against me....last chance.

Left voice mail saying IRS was filing a lawsuit against me....last chance. same thing

I called this number back and they asked if I was Angela and I said yes, so she went on to say she needed to get information from me or there will be a lawsuit filed against me, I told them to stop calling people for they are scam artists, for I know I don't owe IRS nothing, for I worked for the IRS and they don't this stuff that they are nothing but fraud people and I am turning their number in to the real IRS. Actually I don't work for the IRS but I did work inside the building for I was an credit union employee.

Called my direct line at work, twice.  Computer recording representing to be from the IRS and threatening a lawsuit, telling me to cal their long distance number.  I never give my direct line number to anyone, certainly not the IRS, and they would have called my home or mobile number first.  Obvious scam of some sort, but I am not going to call them and feed their evil. If the IRS wants to file a lawsuit, they know where to find me - and I have no issues with them that I know of.

Same as above-why is this legal!!!
