Springfield City Utilities review: asking for large deposit 1

After being forced into bankruptcy due to medical bills, our city utilities company, decided to close out our account, use our deposit to do this and open a new account and ask for a very large deposit to be able to keep our utilities on, all this was done with out notice or a phone call or warning of any kind on our behalf, I found out by getting on line to pay regular bill like always and notice a final bill had been made and our deposit had been used to clear the amount owed, then I called they told me what they had done, then on top of that the rest of the deposit they used that should of been sent to us as a refund, was kept and just added to the other deposit they are requesting from us, causing us alot of stress and grief on how they could expect such a large amount of money from us with no warning or notice or anything, the deposit that they ask was 3 times the amount of any one utilitie bill it would take us 3 months of utilities to even use up such a deposit. I wish there was someone that would stand up for us poor folks when something like this happens.
