CONCISE
Hi, I’m following up on the desk expected on September 6. Please confirm the revised delivery date by September 10 so I can plan to receive it. I still want the desk. If you cannot confirm delivery yet, please explain what is outstanding and when I can expect your next update. Thank you.

FIRMER
Hi, the September 6 delivery date has passed and I still have no revised date. Please provide a confirmed delivery date by September 10, or explain what is preventing confirmation and when you will update me. I still want the desk and need a clear next step.

REVIEW BEFORE SENDING
The dates and request come from the sample brief. Neither version cancels the order or claims a refund was promised. This is a draft; nothing has been sent.
