Not Very Happy with Discovery - Oncology Dept.

I have been going to Discovery walk in centre in Durban from December 2015, emailing , phoning . All i get is a reference number & nothing after that. I see different consultants & explain my account query with them & always get different answers like its a computer error , i need to furnish certain forms ( which i do ) or motivational letters from the Doctor. All these are supp**** at the walk in centre . I have been told it will take between 2 to 3 working days . A week later there is no feedback then i drive to the walk in centre. Guess what have to send forms again & sometimes another form is requested.I don't see why certain codes are not paid when it is on the treatment plan & i do show the consultants. Every time i go the walk in centre it takes between 2 to 3 hours before you are able to see the consultant. On the 3rd February 2016 when i went to the walk in centre i asked for the line manager from the oncology dept. to be present & explained my problems to her. She emailed details again to oncology dept after speaking to somebody . I was assured that i will get all feedback by email or telephone - nothing. I went back the following week on the 12th still nothing .
