Why have did you not respond to the mail I sent, asking you to tell me the tracking number. I want proof that you actually sent the item, so please can you tell me the tracking number.
I have asked you to send me the tracking number, but how come you haven't replied my email? I want to be definite that you have shipped the product, so I need to know the tracking number.
Why didn't I get the reply for the mail in which I requested for the tracking number? Please tell me the document number as I want to confirm whether you really dispatched the goods or not.
