I have two cars usually taking my cars for oil change. Had an appointment at 6:30 on Friday which I made it one week in advance. ( when i was asking I voluntarily aksked for the latest time) I got there 10 min earlier and saw they were almost closed. One of the employees asked me why i was there. I said i had an appointment, but he went that they were about to close and can't take my car. I played the voice message that one of his colleagues left me the previous day and he startet yelling and fighting that he hadn't left me a message. I was shocked and I asked him if I mentioned anything about him leaving me a reminder message then he said'' come on man''. He went in the office, someone else came out and i played the message again he said he would take my car but I knew there was no one bc the first one had already told me. I was disappointed with the way he talked, he wasn't professional. So I took off and left. Never going back.
