Has anybody had a bad experience with VA Choice Program?

I was given an URGENT consult to the Choice Program on 31 Dec. 2015. The consult is for orthopedic surgery, including all pre-op and post operative care. The surgery authorized is amputation of the right lower leg. I was given this because my local VA can't get to it until August, so it meets the 30day+ criteria. So on 12 Jan., TriWest sent me to a semi-retired orthopedic surgeon that specializes in sports injuries, for treatment of right foot pain. Call me stupid, but I can't find that anywhere in the consult. He recommended amputation, but he doesn't do that. It took another month for TriWest to get me to another doctor. After long talks with those people, and repeated explanations of what my consult was for, and that it was indeed labeled "URGENT", I figured they couldn't possibly make the same mistake twice. I was wrong. The exact same mistake, in the exact same way. Following that, there were several phone calls between me and TriWest, the result of which was they said they had found another doctor. They found me a "foot and ankle specialist" about 35 miles from my house, with hospital affiliations even farther away. I was not amused. I couldn't understand why a foot and ankle specialist, when they are supposed to cut all that off. They were still trying to send me for treatment of right foot pain, Clearly not any part of my consult. I discovered no matter who you talk to, nobody seems able to communicate with their schedulers. I had a long talk with the non-VA care coordinator at my VA, and happily she was able to get it all fixed. I have finally seen an orthopedist on 29 Feb., who does amputations, and is willing to do mine. I am expecting a call from his staff with a date for surgery, and for pre-op today or tomorrow. Even still, the utter incompetence of TriWest continues. Yesterday they called me (very unusual for them, they almost never call me) to inform me that I needed to go to the hospital for blood work. I went, the hospital staff had no idea. There was no order for labs, nothing. Another long argument with TriWest! TriWest finally said It was for today, that I went too soon, and that I had a 9:am appointment for today. It is a walk-in clinic, no appointments, first come first served. I told TriWest that if they were sending me on another dry run, that I would bill them for the mileage, and for my time that they are wasting, at a rate of $100.00/hr, for any part of any hour, with a 2 hour minimum. I believe I finally have their attention. They have since called me back twice, to let me know that there was no appointment after all, and that my surgeon would handle everything, and that his office is the only one I should hear from. TriWest expected I should hear from my surgeon this afternoon or tomorrow.
So if TriWest takes this long (2 months) to get me to see the right kind of doctor, and for the reason actually stated in the consult from the VA, on an urgent consult, for someone that is extremely active in his own care, how long could they screw around with the next guy?
Part of the hold-up in getting my surgery scheduled was TriWest not wanting to give my surgeon the authorization for the surgery until he would give them the date of surgery and discharge date. They won't schedule a date until they have that authorization, and the discharge date can't be predicted until after the surgery. I don't know if I have yelled at every supervisor TriWest has yet, but I'll bet it's over half now.
This has been the single most frustrating, aggravating, infuriating experience I have ever had, any time, any where, in my life. I am at my wits end with TriWest. They used to have the Tri-Care contract out here. I think I see why they used to.

I experienced at least two - the first was last May when I was authorized treatment; but, the doctor's office did not receive authorization even though my appointment was 2 weeks after I was notified that I had been authorized.
The second incident has taken place over the past few months where I seem to have had biopsies taken without specific authorization for biopsies. There was no issue with the burning off of my precancerous and other oddities on my body.
