Why is it that this number called me leaving no message and when i try to return the call i'm put on hold for an excess of twenty minutes? Shame on me for staying on hold for so long? Possibly. A better question would be in regards to why this number is calling me in the first place.
A call from this number came in on my landline. I said "Hello" twice. I heard nothing in reply and hung up. I suspect this to be a "responsive number harvesting" operation by a phone spammer.
