Negligent nursing team and poor account-related admin

We wanted to do a peanut & tree-nut allergy test for our 4 month old baby. We told the nurse at Pathcare (Mediclinic Bloemfontein branch) why we were there, and it was also indicated on the doctor's form.

The nurse ended up doing the wrong tests (a skin ***** test for inhalants). The nurse and her assistant also looked very *********** and ended up fumbling and wasting lots of time whilst they were busy with the tests (they even dropped too much of the positive allergy indicator on our baby which made him itch all over). It even seemed as if the nurses assistant got some on the job training whilst they were busy - the nurse had to explain various things to her assistant whilst they were in the midst of their test procedure. It really should go without saying that they should train their staff on somebody's 4 month old baby (who was crying uncontrollably due to their unprofessional service!).

Afterwords, when they gave me their feedback form with the test results - I saw that they did not test for peanut / tree-nuts. When I asked them - they were unsure of themselves, but said they were sure that the tests they did was what the doctor asked for.

A few days later, I followed up regarding the unprofessional service that we received and was told that they admitted to the mistake would not invoice us for the work as it was their mistake for doing the wrong test.

Following this, they actually claimed the tests from my medical aid. I'm waiting for them to reverse their claim.
