"Dont seem to care"

Really difficult to get through on the telephone its always engaged when I ring (I try not to call at 'busy' times) Found one particular Dr to come across as uncaring and did not seem to be listening to what I was saying - didnt seem to believe I was in pain as I could do normal everyday things. I'm considering changing GP's as I really dont feel listened to by the GP's and that because i'm young there's nothing wrong with me and I should just basically get on with it.
