I am looking for owner info too - I've received 2 calls to my work phone number, for the past 2 days in a row - I did not answer. MS Outlook shows a "missed call from QUINSTREET". I Googled Quinstreet and it says, "QuinStreet is an online performance marketing company providing technologies for businesses to identify their targeted audiences." I don't know if that is who is actually calling me though since the phone number seems to come from Palmer, TX, but QuinStreet shows to be in California.

keeps calling and never leaves a message...called back...something about Quinn Street Marketing

Got a call today. Saying they are from "IT HEADS" whatever that is.
Tried to verify my information but I declined. Definitely suspicious

They call my office number 1-2X a day. Never leave a message.

Called my business and asked for me by name. He was following up with me (although we'd never talked/etc before...)   Was trying to get me to accept an Ebook called High Growth Best Practices Guide provided by Time/Warner Business Class. Also asked if I was changing any internet or phone providers. Did provide this number as a callback, so it's probably not spoofed, but just forwards to one of their offices.

Declined book, and presumably, getting my email on Time/Warner's subscription list.

QuinStreet is a marketing company, and appears to have several locations around the US (although not Texas, despite the phone number).
