Vodafone has been upgrading the self-help services available to its mobile customers and is expecting fewer calls to its call centre staff.
The telco has dropped its unpopular $1 per call charge for prepay users calling customer service.
Vodafone spokesman Paul Brislen said the company was "rebalancing" its relationship with Salmat.
Chief executive of Salmat's contact centre division, Andrew Hume, said the adjustment process was typical in an outsourcing business when a client's volumes changed.
He said about 200 staff were employed to answer calls from Vodafone's customers.
