Paid my final bill on my old property only to be sent another notice more than a month later claiming I owe more money and they sent it to collections before giving me a chance to contact them, the letter was only printed 10 days before they tried putting a lien against my new home and it was sent by regular mail so how did they expect me to receive it in time.

They are crooks and I can't wait to be off-grid in my new home.
