Meter number scam call, They disguise their number using 'Voice over Internet Protocol', Firstly an Indian lady called on *705 and mentioned 'meter readings' so I hung up, Then she called again from a number in 'California' asking why I'd hung up on her, So I hung up again, Very annoying, I work on a busy switchboard at the head office of a company, They obviously target us because we own a number of properties so I get about three of four a day of this type of call.
