"Impossible to get a GP appointment"

My GP surgery opens at 8am I have rung continuously since the lines open when I finally get through there is no appointments for today or the rest of the week. I require a repeat prescription because my pain relief has run out and I would like it reviewed so I can have something which makes me less drowsy. This can’t be completed because I would have to see a doctor and there isn’t a doctor free.

Surely why waste a doctors appointment on something  that could just be reviewed. This is a reoccurring theme with the GP practice how can there be no appointments left just over an hour after opening and how can you even get one when it’s engaged for an hour and when you do get through they are all gone. Surely there could be a better system for reviews. I don't believe the current system just isn’t working. I have been with this surgery since I was 5 years old and over the last 10 years I feel it has turned into a shamble.
