Debt collector asking me to confirm my details which of course I won't do

Caller: Scammers

Scammers and conartists wanting personal details and attempt to extort money for bogus debts. Absolute crooks. Ignore and block.

Definitely a scam, can’t even tell me what company they are… just kept repeating “we are a large private company wanting to speak about a private matter” , block the number, if they can’t tell you who they work for then it’s obviously some type of scam

I called back number (02) 8024 9475 reached voice mail but did not say from what company.

I don't owe money but they keep calling
