Got a call from 240-560-2646 this morning (Saturday!) at 9:30. I normally don't answer calls from unknown numbers, but I was asleep and didn't have my glasses on and figured it was a legitimate call since it was relatively early for telemarketers.
The man at the other end said he was "following up" on some information and asked if anyone in my household had diabetes, which is none of his business, but I told him "no" anyway. I figure he's calling randomly looking for diabetics and trying to sell them something.
I have received about 40 calls from this number over the last week. When I answer they don't say anything and never leave a message. Its really annoying.
