The controller was relaying 3rd hand information to the pilot whilst her supervisor was on the phone gaining the information for her to pass onto the pilot and further instructions for the situation whilst the captain was demanding to know what was going on, what else is the poor girl to do
Im not sure how many times she told him that she didnt know what was going on and even suggested he call the company,
Not really sure there was anything else the controller could of done considering the Sup was still on the phone and all she was told was to get the aircraft to go there, park here and wait whilst more info is coming through
