What should I do if my Airbnb landlord won't complete the TM30 for my 30-day extension in Thailand?

The user seeks a solution for obtaining a 30-day visa extension in Thailand despite difficulties with their Airbnb landlord in completing the TM30 form. Community responses suggest that users can handle the TM30 registration themselves with the landlord's ID and house book, or alternatively, check into a hotel that will comply with the registration process. Some comments note that Chiang Mai immigration may not strictly enforce TM30 registration for tourists on a 30-day visa exemption, and documentation needed for the extension includes the TM7 application form and passport copies.
