Got a call today from this number. Did not answer. I was expecting a package from amazon and I got the text and email that it had been delivered around the same time as the call.
The trouble with Caller-iD, is it doesn't actually show the actual number they are calling from and only show the number they want us to see. Blocking this number means denying Amazon from confirming delivery. That is of course unless you don't order from Amazon... then go ahead block whatever you wish...
