I sent a message to the landlord saying that I would renew the lease, but he didn't reply. Nobody answered the phone just now. What happened?

If you send a message to the landlord and then say that you want to renew the lease, but he doesn't reply to your message. Then you called him, and no one answered, so I think it is very likely that he is busy with something. I didn't have time to look at my mobile phone. So this is all possible. Forget it yourself. Generally, if you have a tenant, you will not give up. If a tenant continues to rent with him, he will definitely call you again when he sees you calling him. Just wait for him.
