They've harrassed me too, even calling from local numbers in my region but with this as call back. Very nasty and sounds shady. Similar spiel I've read about from shady collectors... "regarding paperwork just come across my desk regarding allegations..."o
Did you ever find anything out about these so called people ?? They have been doing the same thing to me as well with regards to the local numbers !! They have also been calling my employer ! Was just curiouse .
I have received calls from this same number, as well as my family members. They try to get my social and other information. They get abusive when I refuse to answer certain questions.
