Complaint Review: Dentistry By Design

This Dental office, located just off the 217 Freeway exit in Beaverton is totally unsatisfactory !
First off, the personnel is very badly trained and as I suspect they are the relatives to a doctor (who is a female Persian). They don't speak English well and I personally have been overexposed to an X-Ray radiation, while one of the assistants - a Persian lady, that seemed to have a little, if any, experience in dental medicine, could not take a proper shot and it took her 27 times (!) to complete a full upper teeth film x-ray set.
Moreover, I was going under a simple teeth exam+cleaning and had no idea how much this would cost me, even having a good insurance !
They did not include in the bill to my insurance maybe just a dust off my shoes, to charge for "service", which was horrible and I deeply regret up to now that I did not pick some different place in Oregon for a dental care.
I had to pay $60 at the end of my visit. They assured me that the rest is for my insurance company.
A few weeks later a new charge comes to my home from them, the $80, without any explanation, without any clue.
I tried to find out what this charge is for. The receptionist, a bit irritable, tells me .....CALL your insurance and ask them ! If you don't pay this amount,we simply get this bill to a collection agency and your credit will be ruined instantly !

Today, I received a newly updated bill, for $105 !!!!

They added $25 to $80 and I'm rushing to call them, she tells me that I can pay it over the phone right now as the bill is still NOT at the collection (how do you know ? This came from the collector agency !)
So, the situation is like this - we charge you for whatever, add some extra, so it looks fine, and send a bill to your insurance, the insurance pays what they can and bounces the balance back to a customer - me.
So, for all the fake service extras they add (and this can be anything like I said), you are, the patient, is responsible. Plus, they threat you with collection and try to push your buttons, so you pay finally whatever they desire.
I am just appalled with a dirty businesses like this.
I want people to be aware of this particular place and I am personally NEVER EVER going to deal with them again ! It's completely worthless in terms of service they provide and the quality of it and completely crazy in terms of charging the customer for things which were not even done !
