Called, could see it was a call center. Sounded like a tin cup...the connection. Could tell it was a call center due to all the other discussions in the background. Appears to be part of Allegiance Telecom and based in Lafayette, CA. I told them if it was important call me back otherwise DO NOT CALL ME AGAIN...especially if you are a call center interrupting my Sunday. They called back...called me rude and hungup. Then when they called me one more time. They just hung up.
