I'm very frustrated with my GP practice.
My stress levels are high because DH died recently after delaying seeking medical help for longer than he should have. I appreciate this makes health issues seem bigger to me than they should.
Anyway I had a telephone appointment with GP who referred me for a chest xray (by coincidence the exact same screening that identified DH's cancer, too late).
I've spent literally days phoning the booking line. It cuts you off after 20 mins on hold.
I emailed surgery asking for help. Nothing they can do, keep trying even if it takes all day every day.
In desperation I phoned the surgery to ask for help and was basically told "not our problem" . I was frustrated and worried and explained that it was disappointing that they wouldn't even try to help. I asked them to email the department and ask if anyone could call me, but no, that's not a service they offer. At this point I told them what I thought of the service. I absolutely didn't swear but I wasn't polite and they hung up. 
Anyway I tried a few more days and then contact the GP himself to ask the same thing. This time, it was possible for them to email the department and they've now been in touch and the appointment is booked. Simple.
I know I shouldn't have been rude, but I also feel the need to explain that the whole thing could have been avoided if the response to the first email had tried to be even a little bit helpful.
