Since the doctor appears to be off line I will attempt to help you. The doctor can also add his comments when he logs on.
The first thing I would do is write a letter to the clinic in which you go to. Write down the facts and try to keep the emotion out of it. Being angry only puts them on the defensive, and the calmer you can be, the more they will listen.
This may be due to a breakdown in processes in the doctors office rather than the doctor himself, and they will need to look at their process and see where this can be fixed so it doesn't happen again.
Your next move might be to report this to your local health department. They will perfom an investigation to help find where the breakdown in communication occurred.
