"Lack of quality staff"

I have been sent a second appointment to visit the eye clinic regarding my glaucoma. Unable to attend the last appointment i tried ringing day after day to rearrange. But nobody answers the phone. When finaly get through i tell the receptionist i can not make afternoon appointments as it is difficult to get back to my village.What do appointments do but send for me at 4.20pm on Tuesday 6th september. I tried all day ringing to change my appointment. To no avail. I am unable to attend my appointment tomorrow.Mr D Lawrence
