Ackermans too broke to pay refunds

I bought two schoolshirts at Ackermans, Silverton. Right after the purchase I walked into Pep fround three shirts for less and then went back to return it. As I had paid with my debit card, the cashier told me it was not possible for him to refund me as he had no cash in the store. I then drove to the Grove mall where again, the cashier told me she did not have cash to refund me. I complained on the Ackermans website and one week later, tebogo called me to apologise. I had assumed it was a flaw in their system that they could not refund debit card purchases but she assured me that it was the fault of both cashiers and she would see that it is escalated at HR level and training done again. She told me to drive back to Silverton for a refund. At this point I was very angry but due to Tebongo's kindness, I told her that I was unhappy and expect some kind of repayment for the petrol, time and parking money this exercise had cost me. She promised to call me the Monday after speaking to her manager, bu then again only called a week later to inform me that she could offer nothing only assurance that HR steps were taken. I then expressed that this was not sufficient. I was paying for either bad training or a company that shifts blame to cashiers who very coincidentally reacted exactly the same in the same situation. I escalated this on their website and would you believe they close the call every time?! This is pathetic service. I have no idea why there is even a complaints devision if their problem solving is worse then the initial problem. Six escalation calls were closed today faster then I could make them. Funny that now there is a speedy reaction.
