Keep ringing been blocked now

had a missed call from this number and called back spoke to a man , when i asked who called me they would not tell me who they were until i could confirm who i was or what company they came from number now blocked

I called back number (02) 4302 0220 spoke to a guy but did not say for what company until he verifies who I am.

asking for personal details of a former employee of a business, wouldn't specify who was calling.

Did not answer because it came up as potential fraud. Have blocked this number now.

I called back number (02) 4302 0220 reached voice mail but did not say for what company.

Bloody annoying

no body answers..sounds like a switch board

These people called but didn't leave a message so I called back. The guy I spoke to said it was a multiple switchboard location for several companies.
