No rewards

I have a student silver account with ABSA Bank and I have had issues with the rewards redemption three times. Every time I try to redeem my student rewards, there is some issue and every time I send a query to the complaints e-mail address, I receive the same fixed response that it will be sent to the appropriate department. I am yet to receive feedback, an apology, a solution or even acknowledgement of complaint for any one of the various e-mails I have sent. 1/10, would not recommend. There are other banks with similar rewards programs.
