Did you place an order on an online store and now you're unable to contact them because the store is unavailable? If that is the case, I recommend reading over this Online Order FAQ page which provides next steps and advice for when this happens. Ultimately, if you can't get in touch with the seller directly, you will need to contact your bank or payment provider for them to investigate the order and charge.
I hope this helps, and please let me know if I missed anything!
