Prolong Discharger problem

I bought the Prolong Deluxe kit for my 2010 Toyota Camry Hybrid. The charger unit is working fine. However, the I was not able to get the Discharger unit working at all. Each time I turn on the Discharger unit, the Fault light started flash RED and the unit does not do anything. Press and hold reset button does not do anything.
Talking to George at Hybrid Automotive, he provided RMA # and I sent the unit back for repair. Two weeks later, I received the unit and plugged it in - It still not working as it showed the same original problem (flashing red Fault light). This is very frustrating experience (as I really do miss Amazon)! Called and talked to George, he told me to record a video to show the issue so he can send that to the factory so they can make a decision! What kind of customer service is this when the company sold unit to customer at high price (it is definitely not cheap for the Deluxe kit)? Very disappointed. I am wondering if others have the same problem and how to resolve with the company. Thank you very much for your info
