Who called from 9712565664

Called 4 times within a mintue.. no idea who it is but name popped up as JTN

Did not answer. No message left.

Left message, only got last half of message:

"or press 9 to be removed from our marketing list"

So, its a SCAMmer(tm)

Called cell phone on DNC list.  Answered, but no prerecord or response and the line disconnected.  How can I play with telemarketers if they do that?

No name but keeps calling.....
