Convenient technical limitations has Cotton On taking your money but not refunding it

Today, my wife tried to return 2 items of clothing to the Cotton On store (with the tillslip) in Kuilsriver access park. One of the items having been purchased there. The store is unable to refund the purchase to the same payment form used (i.e. virtual card payment) due to some technical limitation on their side. The the store assistant, Zandile was less than helpful and somewhat indifferent, simply citing "store policy". No attempt was made to offered a solution, no refund given, and now we are sitting with over R1300 worth of clothing and no refund due to a limitation of the company. Cotton On didn't have a problem taking the money, just returning it. This is not where this complaint is going to end and this is a friendly warning. I've had the same issue with a Game store less than 2 weeks ago and the complaint to the Consumer Goods and Services Ombud is ongoing, as it the calls from Game Head office asking me to retract the complaint. You can't make your problems mine. Fix the problem, or offer me a cash refund if you can't but don't require me to spend my petrol money running after you. It doest have to escalate. I'll give you a day before I raise a complaint officially about Cotton On. Oh.. the assistant Zandile gave the name of the store manager as Babalwa but did't give the surname. You may want to train your staff better.
