I am sure Mueller doesnt care but the guy who ignored my emails for 6 months got scared that he will be made redundant, my advice if you ever want something done in EK cc it to several people but be careful when you still work for them, the chief pilot A380 was ignoring my emails and then I went above him, it was all resolved and good for me but of course I received a phone call from him and he told me that I have to contact him first before I write to his boss, obviously I couldn't care less.
