My product, which I sent via Ebay, appears to have been delivered, but it was never delivered to the address. There was no change in tracking for 2 days. When I talked to webchat, they said it was delivered, and when I looked at the tracking, it showed that it was delivered, but my customer stated that it was not delivered. Additionally, the delivery information states that it was delivered to the service center, not to the customer's address. I received a negative comment from my customer due to this problem and if the product is not found, I will have to refund the money.
