Query: Defective product, defective customer service

I purchased this product in March. It broke in October. I brought it to an authorized service center. They stalled for weeks, but couldn't fix it. I called customer service at Thomson (they own RCA now) and they agreed in principle to replace the defective unit. They still haven't followed through. Only if the authorized service center agrees to send them the broken unit will they send the service center (not me) the replacement unit. So my replacement is being held hostage by the same lousy repair place that couldn't fix it in the first place. RCA/Thomson tells me tough luck when I call (they won't return my calls). So I continue to wait while Thomson refuses to honor their warranty. I should have know better, this is my second unit. The first one broke soon after the one year warranty expired. Don't buy any RCA/Thomson products. They don't stand behind them.
