Charge for tests that were never performed

Lancet sent me an invoice 2 months after I went for a kolonoscopy demanding R1597.40 for apparent tests they never performed.<br> <br> I paid the hospital cash for the kolonoscopy including payment for tests of which I received my results on 27th April. There were no other tests performed nor were there any further payments required everything was paid for upfront in cash (no medical aid) including 3 other doctors and a dietician. <br> <br> EVERYTHING was paid up front. I left the hospital with my results from Dr Shutte<br> <br> Lancet refuses to supply \test results"the lady I spoke to has no idea how this account has come about but forced payment pending legal action regardless. <br> <br> They cooked up a **** invoice and cannot backup what they are charging for"
