Feedback and complaints

We are accountable, so if you have any query about our fundraising or if you are unhappy with anything we’ve done, you can call us on 44 (0)20 7501 8920, email supporter@antislavery.org or post a letter to the Head of Fundraising and Communications. Positive feedback also welcome!

What happens after I submit my feedback?

Your feedback will be logged and passed to the relevant department. If you have requested a response we will aim to acknowledge your feedback within three working days. Complaints will be passed to an appropriate member of staff, usually a manager. We aim to resolve complaints as quickly as possible, usually within 10 working days. Sometimes, we may need to investigate the circumstances surrounding your complaint to ensure we take appropriate action. We will contact you to explain this. When the investigation is complete we will contact you. Read our fundraising complaints policy in full.
