Query: Briel Customer Service is Dismal

I was happy with my Briel Cadiz at first. Nevertheless, after 4 months, the unit started excessively leaking steam and water. I sent it in to Briel's service center in New Jersey in May - as of today (Sept. 21) I still don't have it back. I have called, been promised that it is shipping in a few days, more times than I can count. So, I've waited 4 months (and counting) for warranty repair of a unit that was only 4 months old. I've sent a letter to Briel's HQ in Portugal requesting that they send me a new unit, but have had no response. I am not going to purchased a Briel product again.Maybe even more discouraging is that Amazon has been completely unwilling to help in this manner. I am very surprised that Amazon will not hold their vendors to higher standards of customer service.So, if you buy a Briel product - pray that nothing ever goes wrong.
