My water provider recently came out to change my water meter..Apparently it was not working correctly.They sent me a letter (and a bill for over $1,100) saying I was responsible for the last 4 years that the meter was malfunctioning..I was paying the monthly bill all along .I just paid what the bill told me to pay..I was not aware of anything unusual...So they my some sort of off the wall calculation ,telling me what I used ....This is not my fault..I don't feel responsible for their equipment...please advise...Rich B
