well, just got off of the phone with tier 4 (again >..> but the guy that answered said he reviewed my notes and it shows they are escalating it to the engineering department (?) and they would not be able to get back with me until they heard from them. I told him if I didn't hear anything by tomorrow, I would just call Excede because 3 months with no answers is rediculous. Think that will help get me an answer? neither do I, but lets see any way lol.
