Utility Investigation in Private Land Parking Enforcement Posted June 7, 2008 make sure you ask each and every utility supplier if there is an investigation against your name OR your address. cover all the bases. insist (nicely) on clear written answers and in a timely fashion. if there has been switching of utility suppliers write to the past ones as well the present. It may be some billing system error on the part of a utility - but we just don't know. thx. only one thing I know for sure: we are living on the present address for over a year, didn't switch supplier and paid every time, on time. so, I guess this isn't related to the parking [problem]...is it?
