Please, please pay attention to people saying to run away from RF language exchange programs. They are just trying to make a buck. If you think they will deal with you as a real business with respect for customers, you are mistaken. If you are used to dealing with great companies with great customer service and return policies that are reasonable, you will be surprised to learn that EF doesn't care about you as a customer. There is always one idiot out there. Worst customer support ever. Shady business. Research on trustpilot and other places.
