Got this call at 9:44AM on Jan 12. Caller ID read "Any lab Test No". The number is 281-870-8022. They hung up after 3-4 rings. Have not had any lab work done nor any scheduled. Must be a scam. I get scam, collection agencies and telemarketer calls all day long. I don't need anything, want anything nor do I owe anyone anything. I am on DNC but they don't care. They just keep calling. If I don't recognize the number, I do not answer. It is frustrating. One day I got 16 calls, one right after the other, some from the same number.
