Summary
X complained that M&S shared their personal information without authority after incorrectly processing a direct debit amendment form. M&S disclosed X's name to a third party (X's spouse) when correcting the error. M&S notified X, apologized, and offered £300 compensation, which X accepted but later felt was insufficient. The ombudsman found M&S had fairly resolved the matter through proper notification, investigation, apology, and compensation. Although the data breach caused X distress and worry, the actual impact was minimal since only X's name was disclosed to someone who already knew it. The ombudsman upheld M&S's position that £300 was fair compensation for the actual distress caused, not for potential severity.
The Ombudsman's reasoning
The ombudsman found that M&S appropriately acknowledged the error, investigated, apologized, and offered compensation. While the data breach caused X distress and worry, the actual impact was minimal because only X's name was disclosed to X's spouse, who already knew it. The ombudsman cannot award compensation to punish firms but only to put things right. The £300 compensation was deemed fair and reasonable for the actual distress and inconvenience caused, not for the potential severity of what could have happened.
