Vitality Customer Service is Pathetic

Such pathetic service. It has been three weeks of not being able to redeem my discount from the Discovery app to buy a smar****ch. I had a 40 minutes long call with Vitality and there was no solution. The consultant said she would be escalating this issue which has clearly not happened. I have complained also via email and social media which not being helpful. Discovery is behaving like a **** and does not care about solving customer issues. Such disgusting and disappointing service. I no longer see a use for Vitality and will be cancelling.
