Got 4 calls from this number.  I asked who it was and to be put on their no call list.  They hung up and did not respond.

GOT A CALL FROM THIS NUMBER, QUICK HANG UP....CALLED IT BACK, BUSY....WAITED AN HOUR AND CALLED IT BACK, RANG FOR EVER, THEN A CLICK AND ALL QUIET.

Call with no voice answer, just eventually hangs up.
