Who called from 3074594210

Some vacation promotional package was offered to me. I told them I am at work and busy so don`t call me. They said I had signed up for their calls. I hung up on them.

Called me just now and one ring on the phone and hangs up.

Also, I just thought I would call it back, twice. The first time I got a busy signal, the second time I got a fax line.

called me, i didn't recognize the number so i just ignored the call.

This number keeps calling my cell phone while I'm at work!  If I don't answer, they don't leave a message - and if I do answer, they hang up!!!
