Pretending to be a legitimate business, contacted me by whatsapp and tried to get me to pay them. I have confirmed with the business it is not them.

Txt claims to be Daniel from Australian Investor. 3 different messages received over 3 days.
Addressed me incorrectly.
One message contains an email address (gmail address, starting with "basecamp"), purportedly mine, asking me to agree to sending documents.

Texted with my name then "can I get you over the details we discussed" I have no idea who it is! Deleted and reported as spam.
