Conservice Utility Management & Billing review: Utilities billing service

Conservice added Vacant Charges to my bill that belong to a different building and different meter, let alone a different address. I contacted them to fix it, gave them the proof, they realized their mistake, but they are refusing to fix the current bill, stating they can only give me credit for it next month after I pay it. Side note, they also charge me double for the amount of water I use. There is literally a water meter on each apartment, but they don't check them. They just make larger apartments pay more for water.
