Who called from 3124737174

Caller hung up after I said hello.

One of the many robo calls I have been getting on my cell phone.

I called their on line number and asked to have my number removed. I also asked the operator to find out about the 312 calls.

I keep getting calls from this number.  When I try to call the number back to tell them to quit calling me it has a robo voice message about Magic Jack.  Then it says this call can not be complete.  Please check the number and call again.  Total scams!!!!  I am reporting this number along with others to the FBI.  This is ridiculous!
