"Long delay made me miss other appointments"

I’m not happy with the way the Dr made me wait 2 hours to be served. I had an appointment for 8;30 and I only got the help at 10:30. Me being delayed started the previous day when the Dr kept trying to do a procedure on me that eventually failed. This was at Burton, the doctor had to refer me on. But I can say that I’m very concerned about the doctors confidence. I felt like if my Dr is taking all this time to assist me and sounding unsure then how is the outcome. I know it’s always good for professionals to run things with other colleagues at times but in this case why the unnecessary delay and inconvenience caused. I missed all my other appointments for that morning due to this delay.
