Some one not doing there job

Please this is now the second time I'm having issues with pathcare submitting an incorrect tariff code and billing me first. we had to settle this matter by getting attorneys and medical council scheme involved and was resolved by pathcare having to issue the correct code . It was a long and frustrating process. I don't have the time or patients this time. Bill was submitted with incorrect tariff code.this is an in hospital claim and medshield covers unlimited. I am not in the position to submit codes to the medical aid . my wife recovering from emergency c section and premature baby girl extremely underweight still in hospital. Please rectify this issue without having to come back to me. Should the medical aid declare that they do not cover such blood test,then I will pay .currently the claim stands as rejected due to incorrect tariff code. Some one at gatesvill pathcare is not doing thete job. Invoice ***.
