Business ProfileforOrthodontic Experts of Chicago-Pilsen

I Was a patient at the clinic on Pilsen ,and at first I didn't have any complaints when I first started my treatment plan however , before my braces were removed I was suggested to get a fixed retained which was $175 . my braces were removed two months later I was sent home with a retainer which were part of the treatment plan kit one is free . a week after getting my braces removed my fixed wire retainer was lifting and i called in the office letting them know my situation . I was told I can come in for an appointment and replacement for free . I tried getting a sooner appointment no openings were available until the week after so I chose the appointment for the next following week. by the time it was time for my next appointment my retainer had already came out . I assumed when my braces were removed some of the glue was also removed from the fixed retainer . when I got to the clinic the receptionist told me it was a $50 charge just to see the dentist when I am already an established patient and additional to that I had to pay $ 400 just for the fixed retainer , because it was pass 45 days . I implied to her I still had the fixed wire with my retainers and was told by a receptionist **** this would be free of charge . the receptionist in the clinic did not reason with me . she continuously implied i had to pay $450 or no solution would be resolved . I left the clinic called later and the representative **** apologized about the situation , documented what I told her , and contacted the manager . she told me I would get a call back . I've contacted the office twice . I have yet been able to reach a manager this is a very unprofessional place of business . how can I get this resolved ?
