Poor management

Yesterday I purchased a product at the pick n pay in the northern area of Fourways. <br> When I got to my place I realized I was not satisfied with the product, this morning I then went to the Pick'n'pay in Carlsworld, I asked for a refund then the lady who was meant to assist me with the refund Doris asked one the staff to check whether the product was available instore, and as it turned out it was available. She then rudely told me that I should take something else as I cannot get my refund, I was further rudely told that I should drive back to the pick'n'pay in Fourways if I want my cash refund.<br> Bare in mind I provided my original receipt and packaging!!!<br> This is absolutely absurd, how can a customer be told to return their unsatisfactory products where they originally purchased it?<br> What about consumer rights?<br>
