Message left on my home message bank by what sounds like a middle age Australian women, no accent "Vicki calling from Sydney (02) 9806 2414, please return call quoting reference 2001393*** " no explanation as to what organisation or company Vicki was calling on behalf of or her role/position with them or what call was in relation to. Suspect this is either a scam caller or someone who just doesn't know how to use a telephone professionally. Either way a nuisance call.
