Please let us know if you can find cheaper places, cheers
Harvey Norman is the second good one if cant get it from TGG http://m.harveynorman.com.au/lg-g2-32gb-smartphone.html
Only available with purchase at: Optus, Harvey Norman, JBHi-Fi, DickSmith, Allphones and Others* (genuine AU stock coz LG will validate with your IMEI for cashback)
since the box has the IMEI printed, everyone can copy it down but I think it is not the reason as LG would have to check with store info,which would be submitted to them when phone sold to a customer. In your case, you first need to make sure the salesperson didnt give you the returned one from previous owner who decided to bring it back to JB, or the one you got is actually a display model which is never valid. My advice to you is bring it back to JB where you got it and tell them that you cannot claim the cashback from LG, ask to have another one or a full refund then shop from somewhere else, you still have time for this promotion mate
