Bad customer service from Exclusive books

On the 4th of December I order a book online, the English version. On 12 December I received my parcel and was so excited only to realize that they sent me the Afrikaans version, which I already own. I contacted them and their response as just that they didn't have the English version. No one contacted me to ask if it would be fine if they send the Afrikaans instead. When I contacted them to inform them that it is the book I ordered they simply said I must the book to an Exclusive book branch and once they received it at their warehouse, they will refund me. The reason I ordered only online in the first place was because we do not have an Exclusive books branch in our town!
