Mabitsela said the bank gave her conflicting stories, and she was then told the buyer had reported the vehicle stolen.
She called the police as there was a case of a stolen Toyota Avanza in a registration number that matched hers, she said.
"When I tracked it through my cellphone I located it to Edenvale Panelbeaters," she said.
"What is strange is that the file [at the bank] is handled by a lot of people who all acknowledged the fact that proper procedure was not followed from their side and they don't want to put it in writing.
"I don't know whether I should continue paying the insurance on the vehicle and tracking unit," she said.
Wesbank refused to respond to these allegations directly.
Communicating via Bonnie Robertson of Meropa Communications, Wesbank said its customer resolutions department was still investigating Mabitsela's query. "The bank assures Mabitsela that they will provide her with feedback directly once the investigation has been completed."
By the close of business on Thursday, Wesbank had bought back her car and Mabitsela was called to collect it.
