I wonder if you then forwarded a complaint to their manager anyway? I'm pretty sure I would have.

Not a complaint but certainly the manager in question was notified along with "Sid Down" himself. Predictably the caller was not Sid but presumably someone wanting to hack in. The company in question is a Local Telephone service provider (name withheld) and there were parties interested in trying to hack the switches for obvious reasons.

"Sid Down", of course is a psuedonym.

Edit by tye, close UL with /UL not /U
