this guy tries to sound like hes law enforcement and uses words like "charges against you" "detainment" "warrant" "court of law" and the county he is from is unclear when he states it. if this is indeed a bill collector the tactics are questionable, threatening and unprofessional.

received a call today from this number. It was a recorded message stating I should call back regarding IRS. When called, I was asked for my SSN. When I ask why is that needed, I was told, "I can wait for the police and give it to them". Then the caller hung up the phone. 4/9/15

Got a PC on 04/07/2015 AT 12:58 AM MTD. I've been getting a lot of calls lately and when I answer, sometimes there's a "voice recording" that simply says, "goodbye." It's very suspicious like computers are calling peoples numbers in order to find out the location of where the phone is at. I live out of state away from the area code linked to my phone number. This is a "wholesale direct Metals" ph#.
