SBC MESSAGING

I called the number and got a recording.
The recording said they were selling a $40 "family ticket"  good for the whole family.
No hint as to what the ticket was for or about.  They said they were exempt from the do not call list but if I wanted to have my number put on their internal do not call list, I could.
That's all I know... so far

8:45pm.  Picked up and no one was there.  Eventually the other side disconnected.

Got several calls from 408 865 9415. No response, just the same message for the $40 ticket
