8 days has passed since I received the item shipment confirmation, but isn't it odd that I can't use its tracking number yet? I'm sorry for the inconveniences this might cause, but do you mind checking the tracking number again?
It has been eight days since I received confirmation that the item has been sent, but I still can't track the package with the tracking number. Could you please check one more time to make sure it was the right tracking number?
After 8 days passed since you told me you shipped the product, I can not track it by the tracking number still. It is too strange. Sorry to trouble you, but could you please check the tracking number again?
