Another of the famous scam the FDC has warned us all about  - "I'm just calling to update our records, can you tell us if you're still using the ________ equipment?  It's just there, on your desktop..."   This type of scam leads to unasked for and unwanted re-fills of ink cartridges... or office supplies... or IT electrical... whatever they're peddling... it goes on an on.  BUT, when the scammer has been politely warned that we're on to you and please knock it off... and they then continue calling again and again??!!!  That's just RAT FINK behavior.
