I informed my landlord about the blocked vent in my room on Mar 29. She had it checked by her son a couple days later. He said a technician will have to be called. As of today, no technician has come in, despite being assured last week they will come as soon as possible. I get huge temp swings in my room depending on the weather outside. They only gave me a small fan unit until the technician gets here. I have a temperature sensor in my room and I have sent them pictures of the readings.

My lease ends on 4/30 and i offered to extend it till Aug back in Feb (which i haven't signed yet).

What are my options here? This will be unlivable in July if they don't come and fix it. I have started to look for other places to stay
