Raise a concern
Tell us what happened, what you need resolved and how we can reply.
Make the issue clear
Use the contact form and select Complaint. Give any relevant reference, the important dates and a short factual account. State the outcome you are requesting. Do not include passwords, payment-card details or identity documents.
Keep the record
Save your submission reference and any response. If further evidence is needed, the responsible team should explain what is necessary and how to provide it privately. A general complaint does not replace a time-sensitive notice required by an actual policy or contract.
