If you have been online and accidentally clicked on a college site, they will keep calling you checking to see if you would like to enroll in the school. You actually almost "HAVE" to speak to them in order to get them to stop calling.
Someone called asking if I was enrolled in school and was interested in attending University of the People. I've never heard of it and I am not interested. They called again back to back a couple hours later and left no messages.
I received 2 calls from 718 269 7087 and 718 2691645 . I looked up both numbers and both have negative ratings. Don't picķ up. Block the numbers spam or phishers BEWARE.
