It's the Art Institute of Pittsburgh online admissions.  You may have expressed an interest in the past.  All you need to do is call them & have your name and number removed.

yeh! they are a pain ?

Actually, it's South University based in Georgia, but this is a PA #.  I wonder if somehow they share numbers?  I just called the number & South U answered.  I attended this school & transferred & they're calling to see if I want to come back.
