Dr Spies and partners Bloemfontein incorrect diagnosis

Went for a MRI scan on my shoulder. The result from them was that there was a cancerous growt in the bone from my upper arm and that the cancer had spread to my prostate!! Death sentence!! After a lot of blood tests and surgery to the shoulder and a biopsy of the growth, which took 9 days all the results were negative?Iwas billed a co payment of R3720 which I discussed with them that I dont think is fair for a wrong diagnosis they still insit on payment. My family and I went throug heavy trauma!!!
