CenterPoint Energy complaint: Outrageous bill for me

I received my centerpoint energy bill and I had when to the help agency because I had a disconnect notice sent to me by mail and the help agency put a pledge on my account and told me that will prevent it from being disconnect and when I called centerpoint energy customer service the representative said that it would take up to 30 days to be applied to my account but the total amount of the bill was $314 and $207 was applied to my bill leaving me with $100 left to pay so when I get ready to attempt to pay that amount that said I had to pay an additional money that included February and March charges that act like I’m Dick Cheney that owns Haliburton I’m on a fixed income and I can’t afford to pay all that on my gas bill and leave my other bills to be turned off because of non pay please let me pay at least half and pay the other at the end of April my account number is 8792190-4 name Timothy Johnson
