Don’t bother returning it’s a scam!
Don’t bother returning for size change or refund they will never be returned and you will not get your refund. Even registered post, had a follow up by Australia post this is reply Outcome of enquiry: Item with customs in destination country Recommendation: Addressee to contact local customs authority in China Your article is currently awaiting China Border Force clearance. Foreign customs matters are pursuant to laws and regulations between the addressee and their government. Australia Post is unable to contact the addressee or contact a foreign customs service to secure or expedite clearance. Just a scam!! They know this will happen when they ask u to return it 😡
