Discovery Insure: Useless Support

I joined Discovery Insure, incl. Drive, in Feb this year and now have all the different Discovery products. One of the benefits is the Vitality Drive Active Rewards. This does not want to work and I've created numerous support tickets. No one ever follows up and when I try and follow up, I usually get a different support agent or they don't look at the previous ticket history and just give me the same answer that doesn't solve the problem. There is no ownership around a support ticket. After months of trying to get this resolved I then sent and email to their complaints email address; I received a generic message that someone will get back to me in 48 hours (this is now over a week ago). They also say that I can't reply to that email address but can contact the call center (the same one that I'm struggling with!!). I'm beyond frustrated. I understand that things take longer at the moment but this is just poor and unacceptable. I'm hoping someone at Discovery reads this and looks into this.
