Advertise all the benefits but not willing to pay out!

i am most disappointed in Discovery Vitality. All these fabulous benefits are advertised but when its time to pay they have numerous excuses. I booked a flight for Nov in May. I had my phone ****** and therefore didnt have ACTIVE rewards at that time. for which i have a police affidavit. Nobody from DISCOVERY can help me with this since May. Today 14 august I booked a flight for 21 Sept which leave me with exactly 6 weeks to achieve my rewards (this week rewards should be included) but was told I can only start counting from next week. Most unfair!!! we pay a whole lot to have these benefits but excuses...excuses,,, to ensure non payment, I will be considering cancelling vitality !!!
