I've been emailing email@example.com and submitting messages via the "contact us" form on their web site. For three days now, with no response. Not even an automated response that they got my message and are working on it. Is it a holiday in Israel this week? Does anyone know any other email address I can try? I received my Flytrex Core2 but I never received an activation code so I can use their web site. I've checked the spam filter and I had no trouble receiving the automated order and shipping messages when I placed my order.
