Unhelpful Service

I trained to return a Trackpants at Vangate Mall branch and was refused because I didn’t have the slip with the Choice Clothing Bar code on it. I bought the pants 2 weeks ago and found that I only had the receipt showing Choice Clothing, the purchase amount and my bank card used to purchase this item. The person assisting didn’t even look at the slip, she just said they need the slip with the barcode on it otherwise they can’t help. The point is - the proof of purchase I have has Choice Clothing on it - I have my ID and Bank Card with Card number showing on their slip. This was extremely unhelpful to say the least.
