Who called from 7048371096

Recording saying to press something to be removed from list then asking if I want more income -- I hung up at that point.

Called my Boss and said I refered them to her...I have no idea who these people are!!!!! Called the number and, like bob, hung up when they wanted me to put numbers into my key-pad.

they just called me.  like an idiot I pressed a number in the keypad.  what do I do now?????
