Started my test in the testing center at 5727 N 7th Suite 301 Phoenix, Arizona. Roughly 5 minutes in "Miss Madden" (wouldn't give me her full name) warned me about my mask which was on my face but wire was below nose. She approached me as if I just committed a felony. Stated that was my final warning and "to bend the wire around nose so it don't happen again". I was taken back a little at first but fixed mask and proceeded with test. Roughly 20 minutes later my test shut off. At first I really didn't know why but it dawned on me my mask was again on but top was below tip of nose. I looked through window and she was fingering me to come out. Once I walked out of testing room she informed me I was kicked out. Then proceeded to blatantly lie and told me she warned me in the hall as well as in check in office too. Never happened. Once i told her that was my first warning and the other incidents didn't happen she stated " well 1 warning is all you get". Admitting she was lying. Never had a problem until test started. To no avail, I pleaded to them my company spent a lot of money on this and I had traveled from Houston and it would be detrimental to my employment. She continued to lie and had zero care. I've filed complaints with PSI with no response. Worth noting "Miss Madden" was forcing other testers to sign there IDs with a marker before she would accept them. Ids these people have used for years without writing on them.
