Polyclinic review: Complaint

I have paid Polyclinic $188.12 as of April 28, 2022 yet they keep saying I owe them the money. I contacted my bank and my bank faxed Polyclinic the information showing I had already paid the $188.12. It does not seem to make a difference. This has been going on since May and my bank has contacted them and faxed them the information showing it's been paid. It makes no difference, I still get a bill every month!
