A friend removes an unlawful "debt enforcer", who is not a proper certified court bailiff. These people have bought details of (purported) debts, but have no deeds or assignment or novation, and no contract with the debtor, and no court order to show. They are breaking the law by having your personal details. This is how you deal with them (by asking them to leave). Would be awful if it got passed on… a lot. 🤪
