Disrespectful and Rude

Woolworths is usually one of my favourite stores, at which we spend immensely without fail on a regular basis. I always assumed that Woolworths staff was trained in the best manner of customer service, but man was a given a wake up call when my husband advised me of a bad experience he had. One weekend, shopping with our kids and my mom, in a rush at this point, my husband spotted a few clothing items he liked, which he purchased, but did not have time to fit the garments on in store. Well later that evening he took the opportunity to fit on the garments and found the one trouser did not fit the way he liked and decided to return it. A week or two later, way before the return time allowance expired, my husband went to Promenade branch to return the trouser but unfortunately at this point could not find the original receipt but trusted they could track it on system. He was "assisted" by a very rude clerk who told him that as he bought it at another store she could not track his purchase, when he raised his disappointment in this regard, as he needed to credit the item as he did not want it any longer, the clerk laughed at him being disrespectful and rude. She returned his concern with major attitude, as if she was doing him a favour being at work that day. How staff are allowed to treat long standing, good customers like this is appalling. Why at other stores one can exchange items bought on account without receipts and not at Woolworths is unexplainable. Very disappointed customer!
