"Terrible Practice"

Never call back when they say they will or when they do they let it only ring twice then hang up no chance of even getting the phone out of my pocket, or they call me the times I say I’m unavailable. They cancel a blood test then I get blamed for not turning up to it, try to explain and I’m spoken over. Very rude and stressful dealing with this surgery. I have never known anything like it, they don’t seem to care.
