Listen - You are thinking about taking biblical or modern Hebrew... these guys are almost a scam. They offer classes and they are going to reach out to you over and over again when they sense they have a fish on the line. However as soon as you have a problem, there will not be anybody at the phone. You will be dialing in the middle of Beersheba in a well somewhere because no-one will ever answer the line again. They steal money, they are fraudulent, they use switch and Bait tactics, they are dishonest, they will lie to the credit card company, they will falsify any documentation they can make up and I dare you to try and find them in Israel somewhere. You cannot be warned more. You may think you have gotten a decent deal because they will negotiate and negotiate to give you a "good deal", but this is buyer beware!
