Received call - suspected a crank call - after many rings answered - no one there. Caller ID reported  " City Serv Pavin" which is probably (hijacked info) City Service Paving in Placentia, CA. Their number is 714-632-XXXX.
What does the impotent FTC do, if anything at all?

Left no message.  However, the ID stated, "City Serv Paving."

Called yesterday - did not leave message
