President Jacob Zuma's complaints hotline received 7 261 calls between 9am and noon -- or 40 calls a minute -- on its first day on Monday, his office said.
"We are experiencing high call volumes and are spending the day sorting out various glitches," Zuma's spokesperson Vusi Mona said in a statement.
"The hotline has received 7 261 calls from 9am to noon this morning [Monday]. This equates to about 2 420 an hour or 40 calls a minute."
The 40 call centre agents had been fielding the calls in all 11 official languages, spending between 15 and 20 minutes on a call.
The agents routed the complaints to the public liaison offices in the presidency, national departments and provinces, said Mona.
He said the call centre, with the toll-free number 17737, would spend the next few weeks ironing out teething problems, "with a view to having a fully functional service by the end of the month".
