"It feels like no one is interested"

I had a consultation with a very caring dermatology specialist Doctor who put me on a course of treatment to try for one month, and then return to decide if to carry on with it or change it,     I never got an appointment sent to me, so after 3 months of waiting I phoned, to be told they have no record of the paperwork, that the consultant doctor wrote about a follow up appointment, the Doctor is no longer there,  

I feel like the staff member I spoke to refuses to listen to my concerns, and the only response is, the paperwork does not matter, we will get to you eventually,  

I phoned and tried to make an appointment, to be told, abruptly, I felt, there are no appointments,   I tried again the following day, and have now been given an appointment for three months from now -   this is six months,   I do not know if to carry on with the treatment or not?

This is an ongoing condition, the first time I attended was 2015,   so ongoing, and it feels like no one is interested,   I believe this is a terrible way to treat patients
