Milwaukee Pain Treatment Center review: inappropriate service and excessive charges

I went to the Milwaukee Pain Treatment Center to seek chronic pain care for a neck injury. After a pleasant reception, Dr Stein ordered an MRI test -- He also ordered an EMG test but never mentioned it during our interview. I was concerned about the test and was assured it was a "pin ###" type of test - when the test was administered it turned out the "pin" was 3" long and had to be inserted in my neck - the pain was excruciating. Dr Misra talked with someone on his cell phone while wiggling the needle in my neck, causing me extreme pain as a current was being passed through it - he also claimed there was no voltage applied "only milliamps", a current requires both voltage and amperage – I am an engineer and know this, Dr. Misra did not appear to...About 12 days later I received the first bill, for 516.90$ for a drug screening - the total cost was 900$ - plus 385$ for the office call, my insurance paid only part of it I was told this drug test would be part of each visit, and not to worry, insurance would cover it. The statement claimed the 517$ amount was 30 days past due - less than 2 weeks after the test was given. When I called to discuss the excessive bill, the billing person "Bridget" became nasty, mentioned going to court, accused me of calling her a lair on the phone and hung up. After spending two weeks with tests and abuse, I was forced to abandon the center and seek care elsewhere - they never did anything to address my pain - but made it much worse for days after the EMG test. They also charged excessive fees and performed unneeded tests - and charged me for them, doing nothing helpful, claiming I was late in paying them and draining my bank account. I am very dissatisfied with them, and caution anyone looking for reasonably priced care - they seem to cater to insurance claims.
