@ Farfallina; I think I found the answer in your Italian topic. You did some flights / worked for them and you did not get payed, correct? Why don't you ask if someone knows a good lawyer in Germany. Not sure if that is going to work, meaning you had a Lebanese contract and JetAir is a German company. But it might be worth to talk to a lawyer about that.
Hope your ( and all the other) situation gets resolved.
With regards BL
Now your postings make a little more sense
