Bmw VDC Rosslyn security supervisor

Bmw vdc rosslyn is been good company up to recently have been experiencing bad service with the security supervisor at VDC by the name of B something he thinks he owns BMw the way he approach clients at the gate is a disgrace to the reputation of BMW. He doesnt know how to be a supervisor and i made a research only to find that he was fired for alcohol and he was broughtback while other officers were not brought back. Who ever made means to bring him back they are killing BMW. The guy is ruthless he treated me like some criminal while the papers were not done properly but he made it as if i made that paper wrong. I am just a client but to be treated like this no. I rather go to mercedes or Audi if i ever need a car for my business...surely officer under his leadership are suffering from his ruthless behaviour...
