Here is a crazy idea. Get to iRex through there partner. Call or email E- Ink. They maybe no better because they may say we are not their direct customer. However their sales depend on companies that can sell their product. If they are made aware of the non-existent customer service at iRex and how it is making one rethink E-ink products in general then maybe some pressure will come from a place iRex cannot ignore.
