248-283-3969 calls and never leaves VM.

Had to be some Scammer. My Call Blocker senses when a robodialer is calling hundreds or thousands of calls all at the same time and then it disconnects the call after one ring

Scammer.....rang 4 times then stopped (my blocker stopped it); no message left.  "Thanks for calling. The survey you were called for is now finished..."
