The South African Social Security Agency (Sassa) says only beneficiaries who migrated from old Sassa cards to new South African Post Office cards did not receive their social grant payments.
Acting CEO Abraham Mahlangu said the new card system was overloaded, resulting in the technical error. He said other forms of payments, such as those received via bank accounts, were paid without any problems experienced.
Last week Sassa faced a crisis which led to more than 700 000 social grant beneficiaries not receiving their money.
Mahlangu briefed the media on Tuesday following a meeting with the leadership of the National Education, Health and Allied Workers' Union (Nehawu) and Social Development Minister Susan Shabangu.
The purpose of the meeting was to discuss the challenges affecting members of Nehawu and beneficiaries.
Mahlangu said cash payments at pay points were continuing and the technical errors experienced were being managed.
