Do you live in a large complex owned by a big company? In my experience large companies don't even attempt to negotiate.

I've tried in the past at two different complex and never got a response until I walked my ass to the front desk and then was told "we don't do that". My buddy tried that same thing at his complex right at the height of covid when everyone was moving out of the city and still got no response. Two months later they sent him an email asking why he left and what they could do to get him back. I think big companies send any attempts at negotiation straight to the trash.
