Who called from 3122736721

i got a call in november also

I just got a call today asking if I was still in a type of college I don't know how this person got my number

I just got the call and I don't know who it is. They don't leave a voicemail either

I have been getting calls from this number several times a day, and others seems to have been too.

this number calls numerous times. They never leave a message I needed to know how to make them stop.
