"No appointments ever available"

I have been wanting to see the doctor for 3 or 4 different ailments, for going on six months now, I need a new prescription, I think I need surgery on my hand, Im having trouble sleeping, and I want a large mole on my head checking out, looks like skin cancer to me. How do I contact a doctor, the desk staff just say no, what do I do? Please please can somebody ring the doctors and get them to ring me at least, I feel totally ignored, its been months, literally months.
