"Call back at 8 am"

Phoned Monday morning to make an appointment was told to phone back at 8 am. Phoned back at 8 am Tuesday line was engaged until 8.40. At recorded message pressed one to be told this was an emergency line call back and line went dead. Called back got recorded message until 8.52. When answered was told there was no appointments today. I asked what was classed an emergency e.g. chest pains and serious cough for over ten days.Was then given a phone appointment sometime up to 3 pm. Have since tried on-line patient access but the details on-line for me do not match the surgery's ?
