"Running late again"

My recent visit to to Walton neurology clinic was not a pleasant one. I was informed the clinic was running 30 minutes late. After a 90 minute delay the consultant finally came to see me. I asked why the clinic was running so late?.......their reply was the consultant has too many patients. After 5 minutes I decided to cut short my appointment and requested I was discharged from the clinic. I will be putting in a complaint concerning this appointment and mistakes made at my previous appointment in August 2015.
