Beware if you have a medical saving account

My specialist Dr Raksha Sitharam asked Ampath to conduct 8 blood tests.I asked for a quote from receptionist before I went ahead with tests. Ampath subsequently found one test slightly positive and on their own violation did a further 11 tests costing me an over R1000 , Ampath must please refund me the additional costs which were not authorised by me or Dr Sitharam. I will also appraoch my medical aid Discovery Health. to see if they will reverse these costs. I will also have recourse to the Small Claims Court.
