Just another excuse for telemarketers to inflict their sleazy products upon us

This is for Macquarie Card Collections.

I had this too, and returned their call - the initial recorded message said they were "Card Collections" and when I talked to someone it turns out they are the call centre for Macquarie Bank debt collections. So it is likely to either relate to a Macquarie Credit Card or a Jetstar MasterCard (as Macquarie provide and administer these).
