Overcharge and no service

It has taken me 6 weeks to get lancet to change the icd code. Not only that but they also put me as a cash payer and not medical aid rates. Which for the last four weeks I am waiting for thier payments allocation to correct the problem. The real laugh of the matter is that I have dealing with their team leader. When I insist on a higher person phoning me back to get this matter resolved it is a laugh yes they will. They ovetcharge a cash patient by 30 percent. And when you want all of this corrected it takes so long to sort out. If they are bad in this way how can we trust their ability to do the test your life depends on. So yes they made me for this I want my money back.
