Voyager - Your service stink

I am a Voyager member for years and have been as high as Gold. SAA is my choice of airline. Lately I just get no and bad service as a Voyager member. Email send 23 February - reply received 18 March! Email send 15 March - no response, Today I phoned and after speaking to 4 people which after wasting my time and dropping my calls AND putting me on hold for 15minutes I spoke to a supervisor. Atttitude!!!! I had to tell my whole story again and repeat what is in my mail. I then get told don't send emails because we take long to respond! But they don't give the service over the phone either. Why am I a Voyager member if this is the service and respons you receive? It is just not worth it I think. I will change Arilines as if this is the level of service I understand why they are in financial trouble!
