Before contacting us
For faster assistance, include your order number and the email address used at checkout. For a damaged, defective, or incorrect item, include clear photos of the product, shipping label, and packaging. Never send passwords, complete card numbers, or card security codes by email.
Response times
We aim to answer as soon as practical during support hours. Complex delivery investigations, warranty reviews, or payment-provider inquiries can take longer because we may need information from a carrier, PayPal, or another service provider.
Returns
Please request authorization before sending any item. For approved returns, use the registered business address shown below after receiving return instructions. Parcels sent without authorization may be delayed or refused. See our Return & Refund Policy for details.
