This is a debt collection agency who says they are going to "serve" me papers. They are a fake. They don't go to court or do anything of the sort.

The number is registered as a phone service for people in the greater Washington, D.C., area. A call back to the number gives a recorded voice saying that the person at extension 627 is currently unavailable but that they will be with you soon. I received a call on this number today, 6/12/16 and the name of the company is "Account Services". When I called back, it went straight to a voicemail. The message was for one of the previous posters stating that they received a call from a woman and to please leave a message.

Called the number back, it was for a 'pet care ' service for seniors. When I asked if I could be taken off the call log it said "this is not a valid extension". Then I got a fax machine that had no voice mail, I hung up and called the number back.

I received a call from Ms. King stating there was a delivery for Monday and a man named Robert Brown indicated he would attempt to come out between 12-5 to find out when they would be making the delivery. Then he asked for my husband to make myself and my hubby's birthday a few days prior. He asked where I worked and I said I am the head of HR at my residence and it was in my best interest to call back. I told him that HR has his number and to never call my number again.

It was a live caller who started talking before my answering machine picked up. It was a recorded message about research for women who have cancer and they ask me to vote for breast cancer charities. It is probably a scam and a violation of federal law.
