Someone (asian/foreign) calling herself 'Dina David' from NexGen... claims to have spoken to your manager previously but won't tell you what about/give you details what the enquiry is about. Basically my boss said if they won't SAY what they want, he doesn't need to talk to them. Nuisance/scam call.

Same thing scam

Caller: Nex Gen

A company just trying to sell you their phone system

Caller: Nina / Dina

Nina or Dina from next gen wanted to talk to a manager regarding the phone systems, i asked her what about the phone systems she just continued to keep asking for the manager i asked her to email. no email received yet.

Rang twice, then stopped. Assuming it was a scam call from QLD

We have received the same call, too.
