This morning I was flying from KIAD to KMCO on expert server. Shortly after takeoff I began a left turn to intercept my flight pattern. I was then told by the departure ATC controller “IFATC MWE2187” to turn RIGHT heading 310 which was the opposite direction of my flight course. Note that I had already turned LEFT 90 degrees once the controller had contacted me. I responded with “Unable, please stand by” I then began a turn back to the right but it was to late, I was already ghosted. I didn’t even have time to request flight following to KMCO. I am now banned from Expert sever for a week and am a little confused why I was ghosted so quickly. Any help?
