Essenther returns are complicated
Essenther returns policy states that you email them to request a return in order that they provide the return address (within 2-3 business days). However the return address is not provided and they offer to replace the item free of charge "in another sizes or colors" and you can keep the original purchase. On further negotiation with the Hong Kong representative via email, a Melbourne address is provided, and the choice to return or take up the replacement offer. Perhaps there was some confusion but obviously the process is not as straight forward as it should be.
