He said he could not run the taxi business as he was running a bottle store which left him with no time.
"Our business revenue is down by 35% and continues to plummet since Vusi's incarceration. There are eight taxis that are at the risk of being repossessed because the business is not making enough profit," Ephraim said.
He further added that their problems were compounded by the ill-discipline of taxi drivers who have also resorted to disrespecting his niece, who had taken over the day-to-day running of the taxi empire.
"Because she is young and is a female, the drivers do not respect her," he said.
He said at least 15 taxi drivers and their families were affected by Mathibela's continued incarceration
Mathibela, along with co-accused Stemmer Monageng and Elias Skhosana, face charges of assault, extortion and intimidation following allegations that they ran an extortion ring in Mamelodi, east of Pretoria.
