UN-UNDERSTANDABLE SEVICE FROM LANCET

I called my medical aid to ask them that if one of my dependents goes to lancet to do a covid19 test will they pay and they confirmed that they will pay. So i got my mother tested and instead it was not paid due to the fact that a wrong ICD and tariff codes were used(they used blood test codes - 4434) , when I call them with the right code to use, they tell me that the agreement that they had with GEMS is that no amendments for tariff codes will take place after the 14 May 2020 but yet I took the blood tests on the 2nd May 2020. When I ask them to do a credit note and the resubmit a new invoice to the medical aid they refused saying it's not possible and GEMS and denies having any agreement with Lancet regarding the changing of tariff codes and now Lancet is busy harassing me with emails and invoices that I must settle the bill immediately. I AM HIGHLY DISAPPOINTED IN BOTH LANCET AND GEMS BUT MOSTLY BY LANCETS lack of communication and interest to fix and escalate this matter. I would not recommend anyone to use Lancet to get tested for COVID19.
