Failure to re-instate rewards program

I closed my accounts with ABSA in Feb 2013. I have since decided to reopen my credit card. As far as I can remember this took place via ABSA internet sight. I completed the online application for the Rewards Program. When I had completed a message stated that a rewards program was still in place The credit card details were given as per request. I noted that a few days later the amount still did not come off my credit cards. I then phoned the rewards department to find out what had happened. I was told that the debit had been returned as the account was closed. For some reason they had tried to debit one of the accounts that had been closed, and did not follow my instructions for you to debit my credit card. They still have not debited my account and keep on telling me it is under investigation. I really find this totally pathetic. If you cannot run a rewards program properly I start to question how other things work at ABSA. I do have a investment accout as well. If you look you will see that my credit card has money moving through it all the time with no rewards been credited. Do I close my accounts or what.
