CHG805 | Dealing with complaints: Our attitude to complaints
From HM Revenue & Customs · Complaint Handling Guidance
It is important that we adopt a positive attitude to receiving and dealing with complaints. We must never pre-judge the issue and should always investigate any complaint thoroughly and fairly. Adopting a defensive attitude is rarely helpful and can lead to unnecessary escalation of a complaint. It is important to remember that the complaint is almost certainly not directed at you personally and you are dealing with it on behalf of the Department.
