Out of curiousity, what is the official channel for reporting a problem with a Karma or getting it replaced? I assume it is an 800 number to get an RMA etc... It might be worth while documenting who you spoke to / emailed. There are a lot of DNNA and Cabridge folks watching this forum (and riovolution) very carefully. If they can find a pattern where support is breaking down, they can at least report it to the DNNA "powers that be"...
