going to the top does get results!! as said even if it goes to a minion.
i was sat in the hospital and getting no where with anybody, no doctors came to see me and the staffing was just awful. god knows how but my sister got the name, phone number and email of the director of the hospital. so she fired off a scathing email and phoned the number. within 30mins of my sisters phone call, i had a senior SHO come and discuss my case.
get an email written and try and send it to the top. but your LL sounds like a total arse anyway.
