same here... calls multiple times a day. I call back and it rings and rings and rings... nobody ever picks up. Very annoying! Is there any way to report this in some way?
I too receive calls from a variation of the number that begins with 404-894 around 7-7:30 in the evening on weekdays. I've always known the 404-894 prefix to belong to Georgia Tech, because I went there. I discovered these calls at 7-7:30 in the evening are actually from the Georgia Tech Alumni Association seeking roll call donations.
Like Nali, I too receive calls from various numbers that start with 404-894. GT Alumni Association sounds about right, because I'm part of the association and it would make sense that they have my number. I'm glad I got the answer here because I don't pick up calls from numbers I don't recognize and they never leave a message. It's very irritating that they call me so often. Next time I will pick up and ask them to never call me again.
