Myriad Genetics Deceptive and unethical billing practices

I was told by my OBGYN since cancer runs in my family I would benefit from genetic cancer test. I completed an online questionnaire to ensure my eligibility with Myriad Genetics and I was eligible. I asked how do I know how much this test would cost and if insurance would cover it. The nurse reassured me that Myriad will contact my insurance and if my portion of the payment will be more than 350$ they would call me and I will have an option to decline the test and they will simply discard my blood sample. No one has called me.

Then, in February I received an Explanation of Benefits from my insurance company reflecting payment to Myriad Genetics in the amount of 1655.59$. I thought its an expensive test, but was glad insurance paid for it. Imagine my surprise when 1 month later I received an additional bill from Myriad Genetics for 535.08$!!! I called customer service, described my situation, and ask why no one has contacted me before running this expensive test, would I know how much it costs I would most definitely decline it. I was told they don't call their customers and this bill is my responsibility.

I was offered two options to help me with paying the bill. First, I could apply for financial assistance (which I declined because I know I wouldn't be qualified based on the income limit) and second, if I pay in full right away, they would be able to give me a 20% discount on the bill. Needless to say, I was extremely upset. I declined to pay right away because I simply couldn't afford it and I told the customer service rep that I will be contacting my doctor's office to let them know what I am dealing with. And this is where it gets interesting.

After the threat of contacting my doctor, the customer service rep tells me "Since you were told in the doctor's office that you wouldn't pay more than 350$ per test, I can discount your bill to 350$ and set up a payment plan. Would you be ok with that?" I was taken off guard by this sudden change of attitude, that I answered "Yes, I suppose".  So now I received my new 350$ bill and will be paying 25$/month.  I am still in shock of Myriad genetic misleading business practices and payment extortion techniques. Given my insurance company has paid almost 1700$ for the blood test, I can't believe this company is going after more money from customers.
