"Utterly poor service don't register with this GP…"

I never had such an irresponsible GP service in my life. I was discharged after treatment from AnE and asked to have a followup with GP in two weeks as I am taking blood thinner medication for PE and its dose need to be reviewed nd adjusted based on my response. I called for an appointment and the GP gave an appointment after 4 weeks, though the instruction was to have a followup in two weeks. Then, two days before the appointment they cancelled it and rescheduled for another week citing silly reasons. They don't care about how critically ill you are and their reception is rude saying that you will be okay and any emergency go to hospital. Is that the kind of service public is looking from a primary care. Such ridiculous attitude is unacceptable in health service. Please don't register with this GP
