Add this to the "We are so happy with Vodafone today" basket... I was told by someone that Vodafone is planning to introduce a $1 charge per call to their prepay customers when they call the Vodafone help desk number (777) for agent-assisted service.
Apparently they want to increase the usage of self service options such as credit card topup, Hot Link and My Vodafone.
If the user select any of these self service options there will be no charge.
Good luck users!
