You asked for your data. They blanked you. Now you escalate.

You sent a Subject Access Request, the 30-day deadline came and went, and the company has not even acknowledged you. This writes a complaint to the Information Commissioner's Office that states the facts plainly, confirms you chased the organisation directly, and asks the ICO to investigate and compel them to respond.

Write a complaint letter to the Information Commissioner's Office (ICO) about [organisation name], which failed to respond to my Subject Access Request submitted on [date]. The 30-day statutory deadline under UK GDPR has passed with no response and no extension notice issued. State the facts plainly, confirm I have attempted to chase the organisation directly, and request the ICO to investigate and compel compliance. Keep it under 250 words and do not include any information about what the data might contain.
