Awaiting order arrival
Keep the product in its original packaging along with all documentation confirming the purchase and refund. You will need this to contact the seller and the payment system.
Check the email you received after submitting your order. It should contain information about the status of your order and the expected delivery date.
If the contents of the parcel are suspicious to customs officials (for example, many identical items), it may be examined further.
If all other options fail, you may need to consider legal action. This process can be lengthy and expensive, so it’s important to weigh the potential benefits against the risks and costs.
