-by chance, only 3-4 airlines play this little game with you, by cashing your money and no giving the service for what you have paid for.They will let you wait and wait and wait...
-instructors and TRTE are not JAA approved (air indigo???) and you will have only problems when back in europe.
-with 500h tt, and 150 or 300h on type, you may not find a job when airlines insurances ask for 1500hTT.
- all they want is your $ and nothing else, expect to get a crap service right after they cashed your money.
-No one here, has landed a good job after paying one of these companies or they would have said I am a liar.
-don't forget to pay your own accommodation, food, transport...
-paying a company is illegal
for all these reasons, I suggest you strongly to stay on the safe side by keeping your money...
