Bad Service

I bought curtains on the 26th of August in Middelburg Mall, tried returning them because I released its not the colour I wanted. I was told they don't have money at 3pm in the afternoon they don't have money. So on the 30th of August I went to springs mall to return the curtains again I was told the same thing that they don't have money it's not even 1pm yet. Sheet street doesn't want to take they very new unused curtains and give me back my money.
