Horrible customer service and poor quality jacket

On the 22nd of December 2019 I purchased a leather biker jacket at the fix in Cityview shopping mall. I paid using my debit card and I was in love with my purchase. Today I wore the jacket for the first time and I realized the stitching is untidy and the back of an arm is peeling. I went to the store and explained everything however, the lady who was assisting me was not interested and told me they can't refund me because I do not have a till slip! To say that I'm angry would be an understatement I'm disgusted by the service I just received and was told I must take something else worth R400... when I told her I don't want anything she seemed annoyed. I then asked her to give me an email address or a complaint department number which she said they don't have! She gave me customer service number which is also useless can't get through to the consultant. Please give me my refund as i don't want anything else from your shop, I'm sure you can see on your system when the purchase was made surely there's a way to help customers then to dismiss refunds because there is no till slip.
