Really new to this site and realize Leon has provided an answer and the question is seven months old but really felt the need to weigh in on this subject for personal reasons. I am 68 years old and have been under a number of doctors care for the last 20 years. During that time I have had had some great doctors, good doctors and really poor doctors. I strongly suggest you do as I have done-simply tell him or her that you appreciate their opinion you will find another doctor. Any doctor who refuses to allow a referral, under the conditions you described, needs to go home and decide what they want to really be since their ability to be a "great" doctor is absolutely non existent. Really easy to "fire" your doctor..
