"I ordered a box of wine at the end of last year and it was sent to the wrong address. Then I contacted the person that handled the order but he was leaving the company so I got caught in the transition without getting my order. The new person in charge, John Mangano finally answered my calls and agreed to send me a new box, 2 months later I still hadn't received it, he failed to ship it on 2 or 3 occasions because there was always something wrong with FedEx or the weather in Napa. Last attempt was to ship it next day (overnight) to which I said repeatedly not to send it on Friday because of the risk of it getting stuck during the weekend at a FedEx warehouse and this will defeat the purpose… guess what, yes, I was right, the box was tendered to FedEx on Friday, and got stuck at a warehouse in Memphis during the weekend and now I’m refusing the package, I called twice, sent emails and everything has being ignored… Terrible costumer service, shipping practices and nonexistent ownership and willingness to make things right. If this is any reflection of how the quality of wine will be moving forward then that is a shame."
