ConService Utility Management And Billing Has been overcharging me for 1 year 3 months and will not fix equipment nor rebate me overcharges Logan, Utah

Conservice has been estimating my water usage for over a year and after coming to my apartment 3 times has not only NOT fixed the problem but has refused to reimbursement for overages.  They have claimed to have reported my defected meter reader to Greenhill Parish Crossing Apartments but the management claims they have never received any notifications. Some one is not being truthful. I am not the only user with this issue and with each apartment that is leased here, by bill goes up as they are 'guestimating' my usage based on the entire complex. They have been unresponsive to my calls and the calls by the complex.  They have even claimed to have fixed the problem once before and teh head office in Utah still cannot get a reading.  This vendor should never be used.  They are not customer oriented and have even given two different stories, depending on who they are speaking to at the time.  My current water bill is 3 times that of my previous apartment and I am here less often due to travel.
