Yesterday I called my doctor but could not get his appointment. Hence Today I again tried for his appointment.
I started our conversation with receptionist as follows.
Yesterday, I had called for an appointment but could not get doctor’s appointment, can you book my appointment for Today at 7 pm."
Is my conversation is correct Or Should I simply use simple past tense as below?
Yesterday, I called for an appointment but could not get doctor’s appointment. Can you book my appointment for Today at 7 pm?
I know simple past is perfect here but can I use Past perfect tense to give emphasis on my first action i.e. called for an appointment.
I mean
Yesterday I called receptionist first. And after that I give up because receptionist refused my appointment after checking his appointment diary and then I choose to wait for tomorrow’s appointment.
