Absolute smart - ass , tried the BS on me straight away , I said I know who you are , I don’t owe anything. I said ring my door bell again and I’ll call the police

I got a business card. It was in my mail box.

Put my name on the top line of the card
On the next line says
“Could you please call, ALEX TAYLOR 0412 884 899”
The bottom line
“Time attended 4:30pm Date 8/6/23”

Seems to be doesn’t need to call him

Who is he/they actually? Had someone turn up today with this card and number.

Left a note. Debt collector.

I returned a call from 0412 884 899 but the voicemail didn't mention the company name

Rang back. Process server debt collector who would have no need to call me or act for anyone who would.
Typical rude approach.,.

Debt Collector

I called back the number 0412 884 899 and the guy on the other line did not mention the company name
