Caller: Someone looking for "Gina"

Potential neighbour spoofing and bank scam call
Sydney/ Western Sydney area

Sounds like a normal person calling from a different number me asking to speak to "Gina". they say they are her friends and that they can text her just fine but as soon as they call her it comes through to your number, they will ask you to confirm your number, either the first 3 or last 3 digits or ask you what provider you are with. So far the calls have come from a man claiming to be her husband, a young Indian sounding woman and a white sounding woman. Also a scam call form NAB bank telling you that this is associated with Ginas account and you are being investigated for fraud
