Lancet Refuses to correct ICD 10 code

Good Day

It's been 4 months now. Lancet put the incorrect ICD10 code on the statement for the covid test. This was supposed to be corrected and resubmitted to my medical aid as my medical aid does pay for it. To date lancet refuses to correct the ICD 10 code and they keep sending me smses and emails that I owe them. Someone needs to fix this and resubmit to the scheme. This is very unprofessional I don't have the time to run after lancet to tell them how to do their job
