I called back number (07) 3422 6788 spoke to a woman but did not say for what company.

Caller: Jasmine

Credit Corp Brisbane they crawl debtors face book contacting their friends lists trying to recover debts, illegal bottom feeders, total scam never call them back and certainly never give them cash

debt collector

Caller: Credit Corp Australia

Another parasitic debt collection agency trying to sound all cutesy and helpful. They buy you debt for a song from banks etc (little as 10% of the value of the debt) and then hound you. Ignore and block.

If you have received a call from this number for a family member they will likely have a outstanding debt.
If this caller leaves a message with you make sure you pass it on to the person intended to ensure they know about this prior to being summoned to court.
Options are available for people who are unable to pay the full amount required.
Think about it if you were in debt and about to be taken to court wouldn’t you like to know and have the opportunity to prevent it?

I called back number (07) 3422 6788 rang 5 times then goes to busy tone.

This number calls 3 to 4 times a day. Doesn't leave any message. Next time you get a really fricking loud whistle down the line you annoying punk.
