I recently called 777 to have the 100Mb/$10 plan added to my mobile. The call dropped out just as I was heading over the Harbour Bridge (johnr we need more cell sites!) and just as I was calling 777 back as I passed Esmonde Rd, the CSR I spoke to called me back.
Very helpful, quickly added the plan, asked if I needed anything else then the call ended. 10 minutes later I received a txt telling me the new plan was added as he promised.
Great work Vodafone!
