Water Bill OMG!

Monday we got our water bill and it was $265.25! I about freaked! Dec 07 we used 14,200 gallons of water and Dec 08 bill is 41,000! There is NO way we used that much more water. We thought something was wrong with the meter so John checked it yesterday and it looks fine, wasn't moving. So I called the water dept today and told her to look at my account. She was Wow you have a big problem over there! I'm like...NO Shit! Then I found out that it's not the water companies job to come out and check if we have a leak underground. We would have to hire a plumber to come out. So I told her if we had a leak the meter would be moving and it wasn't moving at all. After 20 min on the phone with her she suggests that I go out and read the meter. That was the problem!! They read the meter wrong, 18,000 gallons wrong! So they are supposed to send me a corrected bill, however I still think something is wrong. It's still too much water usage for 2 people with one traveling all of the time.
