claim

I was seen by a nurse at the virgin active in January 2015, they took my blood pressure&sugar and weight.the nurse didn't explain that it will be changed from my medical aid , I just saw a claim in January.I didn't mind because they did render a service I understand nothing for free but they need to explain to us that is not for free.on the 10 march 2015 I received another claim of r160. It shows that I was seen by the nurse on the 3 March 2015, which I didn't.I went to the gym to complain about it I was promised by the reception that the manager will call me even 2day still waiting for the manager to call I don't understand why they claim again as a gym member I need that money to paid back to my medical aid please.
