01/07/12 - Received a call from this number with the person claiming to be from Origin Energy. They were offering 'Energy Saving Products' free to existing customers, such as power boards and fluorescent light bulbs. They wanted to organise a time to have said items installed.
After this phone call I phoned Origin Energy myself and found, after being put through to multiple departments, that they had no record of the above phone call and furthermore that the last time Origin Energy had an offer like this was in 2009.
Sounds like a scam...
