We returned a $950 wine order the day we received it back in late June of 2016. It is now September and I have not received the funds from the winery. I have send several emails & made several calls, on each call I am told "we are looking into it" and will get back to you. When I ask if I can email the UPS tracking documents showing the wine was returned timely I am told "no". I cannot believe how unprofessional this winery has conducted its business with me. I cancelled my club membership but I am not holding my breath that they can do that simple task.
