Totally ripping their customers off.

Totally ripping their customers off.
Bill went from 162 to 320 while maintaining the same routine of working all day and I'm not even home on the weekends. Called customer service and they said it wasn't their end, i was using more electricity. I said that's not true and i said i shouldn't have to pay 320 a month when I'm not even home but to sleep.
They told me I'm sol.
Thanks jerks.
