Subject: Complaint: Delayed Delivery of Order [Order Number]

Dear [Customer Service Team],

I am writing to express my disappointment and frustration with the delayed delivery of my order [Order Number] that I placed on [Date]. Despite being promised a delivery date of [Expected Delivery Date], my order has still not arrived.

The order consisted of [list items] and was paid for in full. I have been tracking the order and it appears to have been stuck in transit for [number] days. I have tried contacting the delivery company, but they have been unable to provide any updates or a revised delivery date.

I am extremely dissatisfied with the service and would like to request a full refund for the order. I would also appreciate an explanation for the delay and any steps being taken to prevent similar issues in the future.

I would appreciate it if you could look into this matter urgently and respond to me within the next 7 days. My contact information is as follows:

I look forward to hearing back from you soon.

Sincerely,

[Your Name]
