Fake IRS call. They call without knowing your name & don't have any ID or case #'s .The real IRS sends certified letters through the USPS if there is an issue. They do not call you, they do not threaten law suits.
These idiots all use this exact number not only for their dumbass IRS scam, but to tell you that you've been approved for a $15K Loan and to call to get the details. No company name or anything, just pre-loan approval for $15K...I find it very difficult to believe that people fall for this crap...
Got three back to back calls from 312-878-5598... No message left. I see that it is obviously a scam based on everyone else's reports No brains, no headache.
