Who called from 7042289038

Calling several times a day. I don't answer. I called back, always blocking my number. It immediately disconnects. Then I tried for 4th time and it goes to a hold song, saying to please stay on the line... I've been on hold 10 mins. I'm thinking they're junk telemarketers. I've been having a ton of them lately!

this number has been burning up my cell phone and i do not know who it is .  When you call back you get nothing.
