Hi Komlosi,
Phone is often a much more effective way of contacting suppliers than email. Suppliers often have a backlog of support emails to deal with, so it may take a few days for them to get back to you. Whereas with phone, you get priority straight away. Here are their contact numbers :
Contact Numbers
USA Toll Free: 1.866.448.4843
Direct Dial: 1.480.966.3040
International: 001.480.966.3040 x1
If the supplier still hasn't contacted you after 3 business days, let me know and I will get in touch with them on your behalf. :)
