Just got the call from this number about 5 mins ago. They leave a message stating that "The IRS is filing a lawsuit against you. Please call back this number for more info." Bull to the highest degree. I wonder how many people are getting scared into calling back this scam. I take care of an elderly relative and I screen all calls. If I didn't, crap like this would cause a lot of needless worry. Just block the call if you can. It's a scam to scare you into giving up your information by returning the call and confirming that the phishing job worked.
Two calls from this number and only once left a message. The IRS would not make a call like this nor would they file a suit until after they had tried to resolve a problem with you. This is a scam of the highest magnitude. Part of the message was missing, but the first word I heard was "services"...probably part of a fake company ID.
I got the same call today. Also, I recieved one last week. I know that this is a scam. I would like to call them back and give them a few choice words! They deserve them.
