Dear directors or whoever is in charge of the service, please note that you do not have permanent mechanics. I have been served by you since 2009 and not only me. Since 2015, I and many of your other clients have disappeared. Are you not interested in this moment? I meet mostly all your mechanics on Hyundai and there's a queue for them, or else you have an empty HUNDRED. The last mechanic (more than a little) who understood left, as I understood it, because of some (smart) leader.
Come to your senses before it's too late. Maybe the problem is completely different. Stupid leadership is one thing, but when a stupid leader. I'm surprised at your approach to business.
