Telstra Business Sales Agents. They work on behalf of Telstra Business. These guys are the real deal and have been contracted by Telstra for the past 10 years to do their telemarketing work. I didn't believe it either until I spoke with a Telstra Rep who confirmed who they were.

Claims to be from telstra, sold a package that doesn't exist. on chasing it up changed my number from boost to telstra and now it is blocked completely. currently on the phone to the ombudsman

Telco Services Australia Pty Ltd, package deal reseller for Telstra? High pressure sales.
