Treated unfairly

Hello I have been sending tons of emails since the last year around August the latest, the people took long to respond to my emails and they gave me a ring they promised to sort out my problems as soon as possible, it February the 23rd today still got no proper response from them , I sent and email in December they told me that they only have one assessor and that assessor is still busy with my investigation, I tried again to contact their office they only rep**** once and told me to at least give them a week so they can gather all the information I need from them and what I need to know it is the end of full two weeks but still got nothing from them I even asked whether should I go there in person maybe their help would be different and much more easier for us all, I still got no response until today they are very quiet and not helpful at all , how do they help the rest or other people? Their investigation took 7months and yet I haven't got any response like really ? They treat us like **** and they are not helping at all
