VAAL TRIANGLE - SASSA grant beneficiaries using the Postbank-issued gold cards have been requested to withdraw their benefits from retail merchants this month. The Department of Government Communication and Information System said in a statement the suspension of the service comes after the Postbank uncovered a series of network attacks by criminal elements on its system. The Postbank has assured customers that a dedicated team of professionals, assisted by experienced external experts as well as law enforcement agencies, have been assigned to deal with this challenge. SASSA beneficiaries using the Postbank-issued SASSA gold cards are requested to withdraw their social grant monies at any retail outlets nationwide that provide the cashback functionality. These include Shoprite, Checkers, Usave, Pick n Pay and Boxer.
