Wrong crown, scary dentist: What can I do?

I recently moved to a new town and picked one of my insurance company's
prefered providers. I had a broken filling that was bothering me. Well,
a request to file it led to a filling which led to a root canal and
temporary crown, which seemed fine. But a couple days ago, the dentist
put in the permanent crown and after a half hour of glueing and
fiddling (he seemed to have trouble getting it to fit) he says what a
good match it is, hands me a mirror and tries to rush me on my way. The
thing is, it was originally a pointed canine tooth, and was now
replaced with a rectangular tooth that bore no resemblance to the
other. Reluctant to recognize the problem, he finally said he would
file the opposite (real) tooth down to match and lowered the seat and
reached for his drill. I insisted that he not do that, and make the
crown correct (as the temporary was). He argued that it was too late
for that, and it was an "aesthetic concern" and a matter of opinion,
and that if I wanted a pointed tooth I should have made that clear at
the beginning. I argued that, by that logic, he could have installed a
green tooth and insisted it was my fault that I had not requested
white. He finally relented and said he'd use the temporary impression
to do a new crown and install in three weeks. Meanwhile, I have this
weird square one in my mouth that's also too thick (from front to back)
and the porcelain doesn't reach the gumline (metal showing). Can this
mess up my other teeth or gums over the course of three weeks? What are
the chances this guy will get it right and not insert a monkey tooth in
my head next? I'd go to another dentist but I already handed over $700
after the first appointment (they tried to extract an additional $600
this time, which I refused under the circumstances). I'd like to cut
and run, but this guy still has the temporary and impression, so that's
the only record I have of what my tooth should look like. Anybody who
can provide advice on what I should do at this point, I'd much
appreciate it. Thanks.
