City of LaGrange Georgia utilities Utilities rip customers off! Internet

I have had problems with the City of LaGrange Ga. utilities forever! They came in several years ago and put in new meters. Untill then my bills were resonable. Now my electric fluctuates from $150.00 to $400.00 and my water/sewage fluctuates from $40.00 to $100.00. There is no difference in our usage. I have had the city to check the meters and they said their meters are correct. I have done every upgrade known to man on my house over the years; new doors and windows, total reinsulation of my house, new heat pump and duct work, new toliets, all appliances are energy star, replaced sewage lines twice, replaced all plumbing. There are no water leaks in my house as we check for this on a regular basis due to the water bill fluctuating so drastically. I had problems with seweage backing up for 2 years, that is why the sewage lines have been replace twice. The city would come and check and as always said it was my lines. I don't even know how much I paid in plumbing bills to have it checked multiple times! When the county buisness across the street started having the same problem the city came in and put some kind of line at the street and I haven't had a problem since! Also I had a water pipe that burst under the sidewalk and even though the city owns the sidewalk they said I was reponsible for replacing the pipe! I have spent thousands of dollars and I am still being ripped off on a regular basis. Don"t you think changing the meters did something. Also don't you think the sewer problem was the citys fault and they lied to me?
