Customer DON'T Care Department

Everyshop sent me the wrong item. They only have two colours of said item. Yet it was so difficult for them. When I email to complain and bring their error to attention, they reply a day later asking me to go into my profile and log a return as if their error is my problem to resolve. I then called customer care and was told the same thing. Why bother having a 'Customer Care' department when you expect the customer to resolve the matters themselves? When you make an error, apologize and take responsibility for it. Don't make the customer clean up your mess.
