NOT PAYING CLAIMS

I went to the emergency room on 20 June 2020. I called in on 22 of June to tell Bonitas I was there, however i made a few payments to the hopital that Bonitas did not cover and didnt have a problem with. Now almost after 3 months I get another email from the hospital stating n need to pay another Bill which Bonitas had declined and was rejected because i didnt let them know 48 hours after I was at the emergency room which I did and the consultant over the phone never told me nor gave me a number or anything. This is unacceptable and hope nobody else had this experience i received.
