President Jacob Zuma on Sunday promised to set up a presidential toll-free line to allow people to lodge complaints with his office.

This would allow them to avoid going through their local councillors, he told residents of Soweto during a visit to the Hector Pietersen memorial.

"The ANC's about truth, there's no question about what the party does."

Flanked by Gauteng Premier Nomvula Mokonyane, ANC provincial chairman Paul Mashatile and Johannesburg mayor Amos Masondo, Zuma laid three wreaths at the memorial. One of the them had the letters ANC spelt out in yellow daisies.

"We came here to thank you for voting the ANC into power," he told an excited crowd of hundreds.

He said he wanted to begin his visit in Soweto because it was the "face of South Africa" and the home of the ANC. Most people in the ANC leadership had come from Soweto, he said.

Zuma said he wanted to do what he had promised, and that was keeping in contact with people.

One elderly man, Gabriel Sekgotho, was given the opportunity to voice his complaints to Zuma. He said "his millions" were being spent by officials and he was trying to get his money back. Zuma called him onto a stage that had been erected for the occasion, to get his details and said they would deal with the matter.

Earlier Zuma visited the Grace Bible Church to thank congregants who had prayed for him ahead of the elections.

Zuma's tour would move to Johannesburg's Alexandra township next.
