gentili signori,
è Impossibile aprire il link con ili Mac.
Non so come rintracciarvi,ma comunque ieri, alle 11:50, in casa c'erano ben 3 persone presenti, quindi o avete sbagliato indirizzo o avete suonato ad un altro interno.
Fatemi sapere come rintracciarvi, mandatemi un numero di telefono.
grazie!
