Who called from 7202409740

Never seen number

This number and 2 others exactly like it (except a couple of digits of on the last 4) called me 3 * in a row and then hung up. It only rang once each time but EXTREMELY annoying!!!!

This number called,when I answered I got no response then I called the number back and it didn't even ring!!!!!!!

Got a call from 720-240-9740 & 720-240-9785 - (DIDN'T ANSWER THEM) but thought I would share with all!!!!

720-240-9740
720-240-9308
720*240-9785
all these numbers call and when i do not answer leave a LONG blank space on my voice mail, a CB results in a busy signal.
