Company is called Harbor Filing Services. They will call from this number pretending you have or are about to be served and they have a sealed letter with your name in front of it. It is, of course, a complete lie and scam. They will give you another number to call and pretend to be a litigation department but let me make this clear- no matter what garbage they pull they are a collection agency trying to get money on ancient out of stat debts they can do nothing about but will pretend like you are being sued which of course is a violation of the FDCPA. I highly suggest you block them or tell them to F off because no matter their threats they can and will do nothing.
