Who called from 2489961997

Got a call from 248-996-1997 in the evening.  No message left.  When I called the number back, a bad recording said that the number is disconnected or is no longer in service.

Have been getting calls from this # 248-996-1997 - didn't answer and they left no message.  called back and said # no longer in service - how exactly does that work?

Left no message and caller ID showd "unknown csller". Another web site showed the following

Company/Carrier:Cmc Telecom, Inc. - Mi

Call from 248-996-1997.  Caller ID says call from Southfield MI.  No message.
