But an official at the sheriff's office said that the proceeds from the auction fell far short of the R4,3-million Mbuli and his wife were expected to pay the Airports Company of South Africa (Acsa).
The official said a final count of the money raised as well as items sold would be sent to lawyers acting on behalf of Acsa.
Acsa was awarded a summary judgment by the Johannesburg High Court in October last year against Mbuli, his wife Savita and their company Zazise Communications.
The company was awarded an advertising contract with Acsa but failed to pay, forcing it to haul the couple to court.
According to court documents, Acsa should have initially pocketed R5-million but settled for R4,3-million.
The company also claimed that it sustained damages of R182,000 a month owing to the couple's failure to pay up.
About 70 household items, including 10 wall pictures, a TV stand, lounge and dining room chairs, flat screen televisions and home theatres were auctioned off.
Acsa had previously won a battle to seize the couple's six-bedroom and five-bathroom house in Port Alfred in Eastern Cape. The Mbulis had offered to put up the property as security.
The awarding of the summary judgment against the Mbulis was clouded by controversy. In their affidavits Mbuli and his lawyer Eric Mabuza alleged that the judgment was awarded in their absence. This was denied by Acsa's lawyers.
