"Someone" will contact you re your claim

I underwent a medical procedure on the 19th Nov 2021, The initial procedure was to be done in May 2021 however due to COVID cases in the hospitals the procedure was postponed, I contacted the Discovery pre-authorisations on 13-Oct-2021 @11:20 am to redo the authorization, was advised I could use the same number originally provided. A couple of days after the procedure I went onto the Discovery App to check the claims and noticed that the Anaesthesiologist Dr Beeton was not paid - Your plan does not cover this treatment, so we have not paid the claim. You have to pay your healthcare provider. I contacted Discovery to be advised that this was an error on the authorization side and will be corrected, someone from Discovery will be in contact with me, I heard nothing - Made contact with their offices again, the same story - someone will contact me - "Someone" has still not contacted me, I am now getting calls from the Dr re the payment. I would appreciate it if this could be sorted out once and for all that if I am told I would be contacted that this actually happens. This is really poor service.
