"Staff are never there to answer the phone!!"

I have never in my entire life been treated so rudely. I sustained an injury to my sinus in an attack and I am trying to recover in order to breathe normally again. I met with a doctor here who did not read my record at all or knew my history and made a decision without consulting me and whether i was ok with it. When I proceeded to tell him I cannot breathe at all through my nose, I got a 'how do i know it wasn't like that before this incident'? needless to say I ended up in tears in his room and he still didn't tell give me an action plan. On top of that I have been trying to contact ENT ENDLESSLY non stop calling and no one ever answers the phone!! how can this be? I was to submit a complaint and ensure my next appointment is with a different consultant but how can i do this if no one ever answers the phone nor has any other form of contact to be reached on? this is so frustrating and upsetting I just want to fix my sinus. I've hit nothing but walls trying to get through to this department and rather than feel like im in safe hands to tackle my injury, i've instead been treated as an nuisance and a liar. Please answer your phones.
