Who called from 7042572137

I've been receiving calls daily minimum twice for the last one week. Couple of times I picked but there was no response. However the calls continue.

I received 40 phone calls from this number in 1 Day in two seperate hours.  Between 8:53 AM and 9:25 AM I received 13 calls from this number.  Then again between 6:20 PM and 7:05 PM, I received 27 more calls.  During each instance calls would come in on average every 2 minutes.

I keep getting calls from them too. They dont leave a message. Caller ID said a Charity. I think its a con because they dont leave a message. Anyone know who they are?

Have been getting calls from this number and no one is there when I pick up.  If they are that hard up for business they need a different job..

Got a call, said with a low slow deep voice, "H e l l o", then hangs up. Wasn't much of a conversationalist. Eerie.
