I received my order but it was incomplete.

In this instance, please contact your seller first. If the seller has not responded or has not offered to help, you may file a Non-Shipping Seller Alert under the category "I received my items and the order was incomplete."
 
The seller will be informed to communicate with you and will  be informed of the consequences if they do not follow through with the transaction. After filing the Non-Shipping Seller Alert, the order status will change to NSS and the seller will not have the option to change the order status.
 
How to File a Non-Shipping Seller Alert:
 
Go to the Problem Order page, enter the order ID and the option to file a Non-Responding Seller Alert will appear if the following conditions are met:
  • You are the buyer in the transaction
  • At least 7 days have passed from the order submission date (since the order was last submitted or updated).
  • Current Order Status can't be one NPB, NPX, NRS, NSS or Cancelled.

How to Complete a Non-Shipping Seller Alert:

Go to the Problem Order page and select an option to cancel the order. This option will appear 2 weeks after initiating the Non-Responding Seller Alert.

How to Remove a Non-Shipping Seller Alert:

Go to the Problem Order page, enter the order ID and the option to remove a Non-Responding Seller Alert will appear if the order is in NRS status. Removing the alert will set to order back to Pending status.

Consequences:

If the situation is not resolved within 2 weeks of submitting the NSS then the buyer (you) has the option to Cancel the order. Fee credit will not be given to the seller if an order is canceled through a NSS. If the seller has 3 orders cancelled via NRS/NSS (sum of all orders in NSS and NRS status) then their Selling Privileges are permanently revoked.
