SOUTH African IT group Datatec said on Monday it had appointed David Pfaff as a new executive director on its board, responsible for investor relations and the group’s South African interests. The networking and IT services group has faced criticism over its communications record in the past and the appointment was seen as an attempt to bolster its profile among investors. Pfaff — who will also be appointed to the boards of Datatec’s Westcon, Logical and Mason units — was formerly an executive director at the then Anglo American Industrial Corp. – Reuters
