Queenspark Refund

With "the system being down" for three days at Queenspark Langeberg Mall, I can accept the store manager and sales lady's apology for not being able to do sales on account, but waiting in-store for more than an hour to get a refund done on my Queenspark card, is not acceptable! Even worse is the fact that the refund at this stage, 3 days later, still not reflects on my account, thus I am paying interest on the outstanding amount which could be lessened by the refund. All other stores I deal with has a refund showing directly after it has been done. Is there no way to speed up the process?
