I was given clothing for Christmas as a gift that didn't fit me. Went into the Physical Ballito store and they refused to give a refund or even a voucher that can be used at a later date without the purchase receipt, even though the Cotton On tag was still on the item and their computer system recognizes the item and price (they had nothing else that I liked in my size - at the time).
Returned an item at another clothing store brand without any issues whatsoever.
Will no longer support Cotton On!
