Quick Template (Short)

Hi [[NAME]], my order [[REFERENCE]] was due on [date] but hasn't arrived. Please provide an update and a new delivery timeline immediately. Thanks, [[YOUR_NAME]].

Formal Version

Dear [[NAME]], I am writing to formally notify you that my shipment, reference number [[REFERENCE]], which was scheduled for delivery on [date], is significantly delayed. As of today, I have not received any communication regarding its status. I request a detailed explanation for this delay and a guaranteed delivery date within the next 24 hours. Please treat this matter with urgency. Sincerely, [[YOUR_NAME]].

Friendly Version

Hey [[NAME]], hope you're having a good week. I'm a bit concerned because my package (ref: [[REFERENCE]]) was supposed to show up last [day] and I haven't seen it yet. No big rush, but could you check on it and let me know what's up when you have a moment? Cheers, [[YOUR_NAME]].

Firm Version

[[NAME]], this is a follow-up regarding the overdue delivery for order [[REFERENCE]], originally promised by [date]. Your lack of proactive communication is unacceptable. I require a confirmed delivery date and time within the next 12 hours, or I will be forced to escalate this to consumer protection services and seek a full refund. Consider this your final notice before formal escalation. [[YOUR_NAME]].
