That is TrueLocal

I had a call too, but it was just after I got off the phone from moshtix, as I had an account locked issue and moshtix couldn't fix it. so they were getting a Techo to call me back, so I'm not sure if it was the techo's that support their systems.

Funny...exactly the same think just happened to me

Its a news digital media number.

I had a missed call on my mobile this morning from this number - no message left.  Because I am waryy of scam calls, I googled the number, and got nada.  I therefore tried to call the number from my office phone (blocked ID) and got dead silence - not a disconnect signal, nor a ring tone, nor an error message/signal.  Tried a couple of times with the same result.  Anyone know anything about this number?
