Flu Vaccine Claim

I am absolutely appalled at the service received from CAMAF. I submitted an invoice for payment to CAMAF, for a general check-up with the Dr. Subsequently I re-submitted the invoice detailing the general check-up AND a flu vaccine. CAMAF is now requesting a motivational letter detailing why the invoice has changed. Surely they can read the additional line item on the invoice and see why it has changed? Nor will CAMAF allow me to submit the flu vaccine as a separate claim. Trying to get a supervisor to call me, appears to be an impossible task. Ricardo, thank you for our 45 min long chat, it has been shocking and torturous wake up call to CAMAF. Not sure why I am paying these exorbitant medical aid costs when I am only trying to claim R130.
