Bad Attitude at Giovannis at Eikendal

It took 2 days of trying to get hold of someone at Giovannis Restaurant at Eikendal Winery. EVENTUALLY got through via the operator. Had a waiter answer the phone and he asks, "What do you want?" Wow! So I then spoke to a manager and he said that their phones are working fine and that I couldn't get through because there must be something wrong with MY phone. Really?! So then why could I leave messages that no one responded to, or get through via operator?? Such a bad first experience that I changed my mind in going to eat there.
