If your tracking shows that your package was delivered but you cannot locate it, we recommend taking the following steps:

• Check your mailbox, front door, back door, and surrounding areas

• Ask neighbors or building management if they may have received it

• Check with your local mailroom or concierge, if applicable

Sometimes carriers leave packages in secure or hidden locations to prevent theft.

If you purchased Shipping Protection, you may file a claim for assistance.

If Shipping Protection was not selected at checkout, ISMÊ Swim is not responsible for packages once they are marked as delivered by the carrier.

For additional assistance, you may also contact the shipping carrier directly using your tracking number.
