What should I do if my landlord hasn't filed my TM30?

The user is concerned because their landlord has not filed the TM30 form, citing a lost residency book, and is considering moving after only a week in the property. Responses suggest that the TM30 filing is primarily necessary for specific immigration interactions, but alternatives exist, such as staying in a hotel temporarily for proper documentation. There's a consensus that the landlord should have acted within 24 hours, and the user is advised to check for potential refunds on deposits.
