Chocks,
Sounds like you are fast exhausting all avenues of communication with Naples. I cannot help you with further contact details for this company.
One way to get a message to them would be to take your flying and your cash elsewhere in FL, fly in to Naples and go and see someone in person.
Since you are hour building you probably don’t have visa restrictions and can quite easily take your business elsewhere – I am certain there will be many businesses only too happy to serve you.
All the best, enjoy your hour building.
