Lacking quality

I recently purchased 4 eyelet unlined curtains, extra length (255cm) charcoal colour, from Woolworths, Menlyn Retail. Upon arrival at my home it came to my attention that all four curtains were infact only 223cm. So I returned them, and although quite frustrated, Woolworths refunded me. Approximately 2 weeks later I saw similar curtains on Woolworths floor: Eyelet Unlined curtains, extra length (255cm) dark grey colour. I requested the sales person to open the package so that I may inspect the product to ensure that it was indeed 255cm. We opened one and it was indeed approximately 255cm. I purchased 4 curtains. I opened the package once again at home and started hanging the curtains. When I was done, I was highly disgusted and irritated to see the bad workmanship and quality control I expect from Woolworths. Not one of the curtains were the same length (the difference is approximately 4cm's!!!) I am not returning it, I expect woolworths to rectify the problem not at my expense or efforts, because clearly they are using a sub-standard supplier. When purchasing a product at a high premium such as at Woolworths, I expect the best quality they are known for.
