North Carolina Utility bill
In preparation for moving out of my old place I called and canceled my account with the gas company. Though I had all my mail forwarded I never received a final bill, and heard nothing from them for 8 months before receiving a regular statement by email. I discovered the company had never closed my account, and claimed I owe $150 for the previous 8 months. Three days later they raised the amount to $350 without explanation. Two weeks later I received a notice by mail saying I owe $400, again with no explanation for the increase.
The company has informed me that they will turn the account over to a collection agency If I do not pay, and I'm not sure how to proceed.
