"Appointment"

I have big problems with my knee. I can't walk at all. Month waiting for the appointment of an MRI. After MRI had to wait another month and a half to see a doctor. But it got worse. Call to get appointment more quickly. I was told that I had to come on February 17th. and can you imagine it?! I arrived at the appointment time but they told- my appointment is cancelled!!!! Without any reason! 'and you can wait 4 hours or we will make appointment on next week'. I can't walk 2 month. Every day with pain and tears. and it's a good attitude to people. Horrible! Like animals! No words!
