Don't rent with them! I was told in an email to had to sign a promise to pay for an amount I didn't have on my NWP bill, mine said $156, they said "sorry, it's actually $850" They told me if I signed something I wouldn't be taken to court. I refused to sign so they added $173 in court fees for filing against me. Blackmail? Yeah I've been a tenant for 3 1/2 years. I'm leaving after this lease is up. Wonder when a good lawyer will investigate this.
