Own a restaurant and have gotten wings from Highla...

Own a restaurant and have gotten wings from Highland Packers for many years, which have always been delivered to us. We have a wing special every Thursday and get a delivery mostly every week before our wing night. Recently they told us that they would deliver them Wednesday, and they did not come. So we waited Thursday morning as they "guaranteed" to deliver by a reasonable time. Still did not show up. Now it is 3 1/2 hours into wing night and we have to tell many unhappy customers that we don't have wings. After a phone call to discuss the issue with them, they decide to tell us that they refuse to deliver to us now. Very poor customer service, especially to someone who has done business with them for many years.
