I don't know how long the current wait is but I would suggest 2 weeks is a very short time.
EZ, and others of course, are undergoing massive expansion at the moment. I wouldn't like to guess how many applications they receive on a daily basis.
As frustrating as it is, try to sit it out a while longer before you approach them checking on progress.
My guess, and it's just that, is to wait another 4-6 weeks before a phone call or email.
