ABSA Rewards *****s from their customers

For the past 4 months ABSA has not given me rewards due to me for transactions on my ABSA credit card. I phoned the Rewards call centre a month ago and logged a query. I was told I would have feedback in 5-7 days. After calling to follow up twice I have still not received feedback or my Rewards that are due to me. Why is it that they are so quick to take their money for Rewards but they cannot give their customers what is due to them. YET ANOTHER HUGE FAIL IN CUSTOMER SERVICE ABSA!!!!
