Business ProfileforMillennium Physicians Association

I was issued a refund check for over-payment of services at Texas Regional Urology (part of Millennium Physicians Association, PLLC). When taking the refund check to their bank to be cashed ***** of America), I was told the check could not be cashed and was "no good". I contacted Millennium and was put in touch with their accounting department. The person I spoke with on the phone said it "was impossible" that the check was bad and "that has never happened before". She continued to gaslight me, inferring they had made no mistake and this was my problem. I cannot bring this bad check to my personal bank, as I will be charged additional bank fees. My complaint is 2-fold: The rudeness and audacity of the employee to make this out to be my fault, and secondly, that the business passes bad checks to patients. This is unethical and extremely unprofessional. I'm requesting that funds be sent to me by certified check as their accounting practices cannot be trusted. I do not want to be sent another "bad check". Horrible customer service, unethical business practices, and a business that clearly lacks oversight.
