I n c o m p e t e n c e and no supervision

Since last year I am trying to sort out an account but unfortunately I am faced with I n c o m p e t e n c e on Lancet account department. Lancet has submitted an account with incorrect codes to my medical aid and now they reject payment. Lancet refused to speak to my wife who sort out accounts and always for the last 26 years done so. My wife is the co insured and we married in community of property. When I call accounts, the lady I spoke to, Mokuphiwa, has no idea what is going on or have any clue how to work with accounts. I have send an email on 12 Feb 2025 and when I spoke to her this morning, one month later, she hasn't even opened the email yet. Can a senior representative in accounting who has more experience in this line of work please contact me so we can settle this account.
