Minol USA Strongly believe I'm being overly charged with our water bill in our apartment Addison Texas

 Recieved our first water bill and couldn't believe the charges in a small one level 1000sq ft. apartment with two adults and 3 children.The bill was $121.00 the first month and I recieved our second bill for $119.00.I talked to my property manager and she said that was high foe an apartment,we then called the company and after being on hold for almost a hour I finally spoke with someone who was unable to answer my question and told me that the meters are accurate and if they send someone to check they will charge me a fee.I had an audit done inside my apartment and there were no problems or running water anywhere........I lived in a 4 bedroom home with 5 people for 8 years and my monthly water bill and sewage was never over $75.00.....I feel that somethings not right and I'm being over charged.....Help!!!!
