PSI Services review: PSI Testing Center & Customer Service

PSI has the worst customer service so far, I scheduled a test for March 05, 2024 at Triad Aviation Academy-1030 PTI drive, Greensboro, NC 27409. The exam was scheduled for 9 am. I went to the center and I was told the center doesn't take exams on Mondays and Tuesdays. there was one guy and he told me he is off today and just came to pick up some stuff from the office. I called PSI from the test center and they told me to go back and gave me a ticket number 4027224. I was told I will be contacted within 24 hours, but no one contacted me. I called PSI customer service on March 06, 2024 around 4 pm and spoke to the rep for about 40 mins and then a guy came on line claiming to be a supervisor (fax was the name of the guy). he told me that he will reschedule me without paying the fee but he needs NC Licensing Board to upload the file again. He gave me the number of NC licensing board as well. Today NC Licensing board uploaded the file and I called again PSI for scheduling the exam and spoke to RIYA for an hour but she could not find any notes for waiving the fee for scheduling the exam. She never wanted to put her manager/supervisor online in order to resolve this issue and in fact she denied if there is any supervisor with the name of FAX. So it means the customer services you are providing is based on liars recruited for taking calls. I was wondering such a big organization like PSI is recruiting highly unprofessional staff and making the test centers with unreliable people/companies. Please investigate this matter that why I was scheduled to a test center who was not taking the test on the specified date and why the customer service rep was impersonating to be a supervisor/manager to bluff the candidates.
