Hello,I purchased a "Stainless steel carpet stair cleaning wand" from seller – Trade Me Reference P242241223.There was a dispute about the shipping charge, and the seller claimed they initiated a refund request, but I have not received any refund.I paid via Afterpay, and the seller has not followed through.Could you please assist me in confirming whether the refund was processed or help escalate this issue? Thank you,   Edited in line with Community guidelines
