"Christine" from Wallet Wizard.

Had my full name and asked to verify my DOB and home address. I said I don't have a loan with you and I don't feel comfortable giving out those details.
She hung up.

called our company phones asking for private information on staff members. she was trying to force me to give out the information, after repeatedly saying no she hung up on me.

Exactly same story as above, dodgy Indian woman answered.

Some place called wallet wizard. When I called them back after missed call they wanted to offer me a loan!

I called back, an Indian woman answered and asked for my name.
I then told her I wanted to know who she was and the purpose of the call before giving out any of my details. She said she could not disclose that information until she knew my name. Alarm bells went off for me straight away and I hung up.
The number is based in Sydney area.

I rang once and got disconnected
