Bad Customer service

Universal Healthcare is the worst. I have send through a invoice from a Doctor that was not paid since October 2019 and received a mail from the person I dealt with that stated that she has forward my query to their claims department and that they will get back to me. This was 27 January 2020 and up till now no one has been in touch. We were previously at Selfmed and they merged with Compcare in 2019. Biggest mistake I made voting to join Compcare.
