Call is identified as a data listing service. You can not call this number back because either no one picks up or the operator says to check the number as it is invalid. Scary
I think it's a data service as they said that different companies can use to make calls. I got the calls and nothing like you got but then I got a message in voice mail from this call and it was Boingo Wireless calling me back about a problem I had with their service.
I got a call from that number regarding the recall of Bosch dishwashers installed by Sears. I had asked for a call-back from a supervisor and she called me from that number.
