Misinformed

I normally receive my Vitality cashback for having a healthy food basket by latest 10th of each month. On friday 12th April I called Discovery Health and was told there is a slight delay and the money will be in my account by 15 April. I called again on the 16 April and was told it would be in by 17 April. I called on the 17 April and was told the LATEST it would be in is the 19 April. We'll today is the 19th and STILL NOTHING. The amount I was told is R500 and it was approved on the 10 April. What is going on and who do you trust????THREE DIFFERENT DATES IN SEVEN DAYS. I'm a pensioner and DEPEND on my cashback. I try hard every month to make good use of my Vitality. After all it costs me R360 per month. After being with Discovery Health for 21 years, I would think I deserve better treatment than this?????
