Discovery lies about their own adverts.

I have a discovery life insurance. I wanted to join vitality as it says on their own website and app that you must have a life policy or medical aid to get the 3 months free. Mine was not activated and i asked them why they say no its only for medical aid. But their own advert says otherwize. Dont let these fools bluff you to open policys or stuff with them they lie to youbto get you to join. I even have a screen shot of the advert.
