Shoddy Backoffice and Accounts Processing

2nd year in a row, blood tests not allocated the correct codes for processing. Try calling Ampath, try emailing them. You get through to ABSA, then Discovery, then finally Ampath. No one answers. You keep holding. Then you keep getting blank messages from Debtors, but ICD10 codes are still incorrect. Shoddiest customer interface and back office processing on this planet.
