*********** manager at Foschini Mams Mall

I bought two jeans for my niece, same make but different colours. She likes only one of them and when I tried to return the other jean, the Mams Mall branch manager, Ivan refused to take the Jean back because it did not have the price tag even though I had the cash slip. I removed the price tag because it was a gift to my niece. How do u gift someone and disclose how much you spent?
