Sample Complaint Letter
Dear Customer Service Team,
I am writing to complain about a coffee machine I bought from Brightside Appliances on 3 June, order number 48217. The machine stopped heating water after only two weeks of normal use.
I have tried the troubleshooting steps in the manual and contacted your phone line twice, but the fault has not been fixed. The machine is still under warranty, and I have kept my receipt and a photo of the error light.
I would like a full replacement or a refund of 89 pounds within 14 days. Please confirm in writing how you intend to resolve this and arrange collection of the faulty unit if needed.
You can reach me at the address above or by email at any time. I look forward to your reply.
Yours faithfully, Claire Donovan
