Called left no message. Called back from another line and received an automated message saying "we are currently receiving a high volume of calls. Press 0 for the next operator or 1 to receive a call back on the number you called from." There is no business identification at all so I'm thinking scammers!
This is an UNWANTED marketing caller violating my rights to privacy. I do not answer unknown callers. I will file a formal complaint with the F.C..C as I am a licensed member.
