Correctional Services spokesman Manelisi Wolela has denied allegations that student leader Mcebo Dla.
Homeowners must never pay builder Junior Mnisi of Dyambi Properties the full amount until he has completed building or renovating.
Three homeowners are sorry they paid Mnisi a total of R177000.
Lolo Tsehle's neighbour introduced her to Mnisi. "Even though my plan had not been approved, he urged me to buy the building materials through him. I agreed because he was going to build my house anyway," said Tsehle.
She paid Mnisi about R60000 for building, plastering, roofing and plumbing. Tsehle transferred the money into Mnisi's account before signing the contract.
The contract she signed does not bear the name of the company. She also does not have any receipt showing that she had paid.
Tsehle said Mnisi was a smooth operator who made his efficient and meticulous workers build halfway, then move to do the same to another unsuspecting client.
"His work is impressive and clients would be easily misled to pay upfront if they are as trusting as me," said Tsehle.
She said Mnisi also used her money to buy materials for houses he had previously abandoned.
"Of the 100 bags of cement I bought, I only received 10," she said. "The rest was delivered elsewhere, as was the plastic for my roof."
Mandisi Mdzeke, a single mother of three, paid Mnisi R70000 to build a garage, an outside room and a bathroom. The work was not completed and Mnisi threatened not to complete it unless Mdzeke paid the balance of R18000.
James Mdhuli paid R17000 for work which was left at foundation level.
Johan Titus of Munsieville Hardware in Krugersdorp, on theWest Rand, said he almost became Mnisi's victim.
He said Mnisi ordered roof tiles worth R7000 and wanted them to be split between two clients. He told Titus not to disclose that the tiles were paid for by one client and used for two.
He later found out that Mnisi had not paid the full amount into his account, although he had given him a deposit slip for R7000.
Mnisi admitted that he had failed his clients, but was disappointed that they had complained to Consumer Line.
"I would pardon Mdzeke's misery, but Tsehle should be the last to complain because I did not charge her anything for demolishing her old area."
He said he did not complete Tsehle's house because she had threatened to bewitch him.
