My mother set up a reservation with King Estate on...

My mother set up a reservation with King Estate one month ago for my college graduation lunch. When we called to confirm, we were told that no such reservation had been made. The people we spoke with, specifically Brittany and Amanda, furthermore spoke to us as if we had been lying about having a reservation in a very condescending manner. Ultimately, we were hung up on. Tried calling again and were sent to voicemail, called back AGAIN and were sent to voicemail another time. Unfortunately for King Estate, my parents are members at 3+ wineries and had been planning on purchasing a considerable amount of wine at King Estate. Terrible customer service! We not only plan on never coming back, but we will be mentioning this terrible experience to all of our friends who enjoy wine as much as we do.
