Query: Poor Support

I purchased this unit Sept 2001. Late October it ceased working - no power. I contacted RioVolt and was issued an RMA to return the unit (late November). More than 30 days later I still don't have a replacement. Try to get a live person at RioVolt to talk to - you can do e-mails or internet - nothing else. I'm just sitting and waiting.
