"Phone call"

Following triage from 111 they advised I needed to contact my GP and be seen/spoken to with 2 hours. Regardless of the automated message of “we are at full capacity” it says hold if you still wish to speak to someone. 22minutes later the phone keep ringing and ringing and no one answers. Now I need to take what could be an unnecessary trip to a&e. You need an alternative way of contact if you cannot answer the phone for situations like this. And if a doctors note is required so not to waste time!!!!
