Incorrect Item & Poor Customer Service

I ordered (***) a copy of the Legend of Zelda: Skyward Sword online, but was sent a copy of the Legend of Zelda: Twilight Princess. A simple enough mistake, I contacted Toys R Us to ask if I could exchange the item for the correct one if they had stock, or receive a refund if they didn't.<br> <br> After receiving no response to two e-mails sent to them I tweeted them and was told that the eCommerce department would get in touch with me. I am yet to receive a response.<br> <br> I find it appalling that not only does Toys R Us not seem to know what it is they are selling, I am now down nearly R400 on a copy of a game that (1) I didn't order, and (2) that I already own, and nobody can be bothered to get in touch with me to try and rectify the mistake.<br> <br> I would seriously discourage anyone from ordering from the online store if this is the way they treat their customers when they get the order wrong.
