Generate a Polite but Firm Complaint Letter to Your Landlord

The repair still isn't done and you need a letter that gets a result without poisoning the relationship you've got to live inside. Describe the issue and your tenancy type, and this drafts a letter that states the problem clearly, references your rights, and sets a reasonable deadline, firm enough to land, polite enough to keep things civil.

<task>
1. Generate a letter that: clearly states the issue and the date it arose, references the landlord's legal obligation, sets a reasonable deadline for resolution, and states the next step if the deadline is not met.
2. Keep the tone firm but not aggressive: professional language that signals the tenant knows their rights.
3. Include a reference line at the top and a clear closing with the user's full name and address.
