The HealthyFood benefit is a lie!

I called Discovery Vitality in January to inform them that i have not been receiving the HealthyFood cash back for two years now. They promised to investigate. A week later, i still had net received any feedback. I called to follow-up and they told me there was a problem with the system. The consultant was unable to tell me what the problem was but promised to call back. On 30 January they called to tell me that the cash back for the past 2 years will be paid in within 3 to 5 working days. That did not happen. I have since called them 3 times. Each time they tell me the matter will be escalated. Yesterday the consultant said they will investigate and get back to me by 3:30pm. I'm still waiting. Today i called in again and the consultant basically told me to wait for another 3 to 5 days. I refused to accept that and asked to speak to someone superior. He asked me to hold. After holding for i while i dropped the phone because i thought holding for that long was just really bad service. I'm just disappointed and have made the conclusion that the HealthyFood benefit is a lie.
