Cotton On-No refund on sales items (CPA????)

The said managers competence rivals that of a store assistance and this will be adequately clear why. I had bought 2 sale items on 13 June 2015 at the Access Park Branch. I went to return it this pm. I was referred to the manager. Her attitude was ascerbic to say the least and responded by saying we do not take returns on sales item. I tried reminding her that I was protected by The Consumer Protection Act (CPA), No. 68 of 2008 which says consumers have the right to return unsafe or defective goods and request a full refund for such goods, provided this is done within a reasonable period- no where in the act does it says that it does not apply to sale items. She was not willing to listen to reason and retorted that she does not make store policy. I asked to speak someone senior. Following a phone call to some unknown person she said\this is a once off'. A very small invisible plaque has the returns policy which she pointed to. The sales clerk or the slip does not warn of this policy. This forces customers to keep unsatisfactory purchases. Cotton On is not aligned with the CPA and if this managers response is true the company is violating customers rights."
