Decline authorization AFTER PROCEDURE

I have sent through 2 emails towards discovery with NO response. *** and ***. My wifes procedure for a back painblock was authorized, which included the injections (like in the past). 4 days after procedure was done, the authorization was declined and again few days later new authorization was given. First of all if the authorization was declined before procedure we wpuld not have gone through with procedure.

We have received a bill of R10 000 from the specialist because discovery basically covered almost nothing of procedure. We want feedback in this regard as this matter will be referred to ombudsman as well as media.
