Bad service can break loyalty

As a loyal client to Opel, I was really disappointed with the level of service I received when taking my car in for service. I woke up so early to be the 1st car at the dealership, I mean by 6:30am I was already there. The audacity to take my car and parking it while I sit and watch other cars being taken to the workshop,be serviced and leaving when they came way after me. Had I not stood up and asked why is the car not being attended to clearly shows I was going to leave there when they close. Now I even question had I left and came back, what shaddy things they could have gotten up to. I was going to be given the keys without my car being serviced. Is it because I wasn't Indian or white?????, cause clearly that didn't make me look important enough and those were the people that were being attended to before me. Mind you I always take my car there for service and it has always been a top notch experience. What I noticed this time around was the change of staff members when I got there🚩🚩🚩🚩......I hope the dealership take them to customer service courses, cause they play a very important role in making one decide weather they come back or not. As for me I will never take my car there again. Oh., by the way, I left around past 1pm....from being the 1st person they found when they opened.☹️
