Trash service

I went to Linen 4 U , the one in Boksburg, i bought curtains, towels and bedding and to my shock the length of their curtains are short, the bedding, i wanted duvet cover and the guy who was assisting me i told him, and asked him so many times and he gave me the Duvet set, when i try to use the duvet i bought, it was a sheet, i tried taking it back they refused it as i had lost the slip, they checked the code on their system, it was indeed there's, and told me that it is not packed the way it is packed, he said so much things that they can not take it back.
