"Appointment was cancelled but failed to notify me"

I had an appointment at my practice for an injection for late afternoon.  After turning up for the appointment, I was greeted by the receptionist who said the appointment had been cancelled, and patients were notified by text.

Feeling quite frustrated but still staying polite, I said I received no texts or phone calls to notify that the appointment was cancelled. I asked if the receptionist could double check my phone number, which was correct. The receptionist replied that a staff member phoned in sick, the reasoning behind the cancelled appointments, they didn't know what had happened, and can only apologise and reschedule the appointment. 

The first thing I see at the reception is a notice of how many patients missed their appointments this month. All practices, hospitals, etc tell us that missed appointments cause delays and cost around £135.

I'm frustrated at the complete lack of communication. I live a good drive from the practice and had to make arrangements just to get to the appointment. I also have an array of health problems which impact everything I do.

My treatment has been delayed and again I'm having to make arrangements just to get to another appointment. 

I get things happen which can be out of people's control, but being accountable for mistakes that are totally avoidable needs to occur. 

I feel let down by this practice and would like to see a change in communication.
