Worst service ever

Can someone please explain to me how discovery rejected my maternity benefits when I am almost 1 month of giving birth when I have been paying them, 1 year ago I joined discovery, I gave birth then suddenly discovery didn't pay any of my claims on time, I kept on getting calls and how I will be handed over then I fought with them till my claims were all paid now that I have rejoined them they are telling me about 12 months of waiting period yet the person that was assisting me from the begging said I don't have any waiting period since they had an issue with me, now I am stressed because which hospital will I go too
