A sample answer to question 1

How would you structure a written response to a customer complaint?

I would start by thanking the customer and confirming what they complained about, so they know I have read it properly. I then summarise the facts I found, citing evidence such as call recordings, account notes or delivery records, and explain clearly whether I have upheld the complaint, partly upheld it or not upheld it, and why. If we made an error, I apologise sincerely without over-blaming individuals, explain what we have done to put it right, and give any compensation or goodwill gesture with the reason. I use plain English, avoid jargon and policy codes, and keep paragraphs short. I finish by telling them what to do if they remain unhappy, including their right to go to the relevant ombudsman, with the deadline, and give a named contact. I check tone, spelling and that every point they raised has been answered before sending.

Common mistake to avoid: Using defensive or templated language; missing out issues the customer raised
