Wrong order and no assistance

Made an online order they delivered a wrong order now they make it my problem. They said I should bring the order back to the store I get that but with who’s money , who’s time I made the order online because it was convenient I even made a suggestion for them to bring my order and take their wrong order. Been running after them the whole day today that’s Phumlani mall Shoprite sixty 60 located in Winnie Mandela
