Caller ID: TSC. No one on the line. Returned the call, put on auto-hold (with lovely piano music by Chopin, but not performed by Rubenstein, unfortunately). "Your call is very important to us. Please stay on the line for the next available agent." Message repeated several times before: "Good bye," and a disconnect.
Received a call from this number, said TSC and when I answered it was a garbled message. I just hung up. The area code is from somewhere in Florida I believe,.
