Baycorp don't check information & chase the wrong person for debt.
They keep calling, don't leave messages & say that they cannot look up phone number on their system to remove it.
Had them chasing a debt 15 years ago because I had the same surname as someone who owed money - different first name, different date of birth, different city but same surname!

I called back number (03) 9978 8198 spoke to a woman who said company name is Baycorp.
