Refund

Today I went to mall of the North to refund some clothes my husband bought for our daughter in 2017. Of course I have misplaced the receipt but I did not want a gift card as they were willing to refund me with a gift card. I wanted cash becaus I will not be shopping in woolies and I hardly shop at woolies. They told me that because I don't have a receipt they can't refund me because it's 2017 clothes therefore they have gone on sale and they don't know how much I paid for the clothes. I believe if something goes on sale it should have a red tag price to indicate that it was on sale. But my clothes were bought on normal price because they don't have a red tag... The service I received was really pathetic, the store manager is on leave and he tells me over the phone that I can do what ever that I like about this complaint but he will not refund the clothes..... Woolies I want my cash back because this is my hard earned money that I bought with and I don't want these clothes anymore., I don't care wherether they are from 2017, but I'm still saying that I want my money back, I'm hoping to get feedback from you before I escalate this to the media. I will go to all forms of complaint platforms until you do right by me
