You (all of you!) are spending a very great deal of money to get the service you are looking for, whether we're talking about ATPL groundschool, PPL, or a full fATPL course. Always remember that you are the customer; no flight training school is doing you a favour by taking your money!
If you have problems communicating with your intended school, then be prepared to withhold your custom. I don't mean to suggest that you over-react to the kind of temporary problems that can affect any business, but don't let their problems become problems for you.
Perhaps most importantly, don't give anyone any money without establishing (by personal contact - written or by e-mail) exactly what it is you're paying for, when it should be completed by, and what services you expect and are paying for.
Naples seems, by reputation, to be a good school, but don't let them - or anyone else - get away with poor customer service.
