@Noel_S , as per your post:
- "Township water department hitting me with a large bill after having billed me wrong for 15 months"
First of all my heart breaks for you.
This is wrong...wrong...wrong.
What the Water Company is doing to you is wrong.
The Water Company billed you....you paid them...done.
You should NOT be back billed by the Water Company.
Now...going forward...as per the Water Company's charges...that is a different matter.
However, I would immediately search for an Attorney to be on your side.
It sounds like you have gone with the "nice" approach and it has not worked.
Now it is time for the "fight" approach.
We wish you the very best!
