Sylvia's Mexican Grill

Our office has always ordered from Sylvias. The food is good. But lately, for the past few months, they keep messing up our order. When we call back to let them know they forgot "a" taco, the supervisors there raise hell. They have no customer services skills. How hard is it to replace one taco they forgot. Today was so bad. We place a large order, and they forgot 3 tacos and a drink. When everyone went to go eat we noticed tacos missing. Three people in our office did not get to eat. When we called Sylvias, The manager got on the phone and refused to send us our order. Our office manager told him if it is to much of a problem to bring us what they forgot, to go ahead and send us what was missing and we would pay for it. He told her NO. He then told her never to call and order from them ever again.Then hung up. Their food is ok, the service and management are terrible. What the hell kinda of Customer service is that.
