According to reports, the Moti family paid kidnappers R50 million for the safe return on their four sons.
News24 reports that the family paid ransom in bundles of cash, after being provided with proof that they were still alive.
It said the boys were handed over once all the money had been dropped off at an agreed upon hiding spot.
However a family spokesperson denied that the family had made any payments.
Last Thursday, Zia, Zayyad, Alaan and Zidan were reunited with their parents, three weeks after they were kidnapped while enroute to school.
Police said the boys were travelling in a BMW when their vehicle was intercepted by two other vehicles.
“The brothers were on their way to school in Polokwane at approximately 7am on Wednesday, October 20, when they were taken at gunpoint by their abductors.
“A group of men with rifles and handguns cornered their vehicle and forcefully removed them,” said national police spokesperson, Brigadier Vish Naidoo.
Last Wednesday, between 10pm and midnight, the boys were dropped off in Vuwani, more than 100km from their home in Polokwane.
Naidoo said the police in Vuwani received a call from a local resident saying that the children arrived at their house saying they were dropped off on a nearby road.
IOL contacted former family lawyer, Philip Smit, who declined to comment. He said he was no longer speaking on behalf of the Moti family.
The Moti family is prominent in Polokwane. They run a successful business that buys and sells high quality pre-owned, vintage and classic cars.
