I'm not going to answer the door to my landlord
What is the point in refusing to answer when your landlord calls?
Because I've already given him a lot of trouble in the past.
Ignoring a landlord is done for many reasons, but it's best to own up to stuff, be it a call or knock. Know your rights as a tenant and don't be a pest moving forward.
Nah, I'll do what I'd like to do.
Ignoring you landlord is going to make the problem bigger than it already is. You should pick up the phone and try to be as kind as you can to your landlord if you have wronged them in the past.
