Scopa chairman Themba Godi said the government could not continue "engaging in meaningless talk" until the last minute with a potential crisis on its hands.
"We can't keep kicking the can down the road. We must comply with the directives of the Constitutional Court. We can't encourage sitting here and talking, engaging in meaningless talk," said Godi.
ANC MP Nyami Booi was supported by another senior ANC MP, Vincent Smith, in mentioning Zuma's name in helping find a solution to the deadlock.
"I really think the IMC [task team] must sit and take a decision because there's no way South Africans can't get their money on April 1. If there's a deadlock, what is the deadlock- breaking mechanism?" asked Smith.
EFF MP Primrose Sonti said she was sceptical that Zuma would provide a solution.
"There is no hope when you talk about the president," said Sonti.
