"Cancelled appointment "

I made an appointment for a review of the medication I have been taking for several months (for my mental health following a near fatal illness) after waiting 9 weeks to see someone, the appointment was cancelled on the day I should’ve attended

When I called to reschedule the visit, I was told I have to wait a further 5 weeks to have my consultation

I don’t believe three and a half months is a reasonable time to have to wait for a review

Assuming the rescheduled appointment is honoured
