Midfielder Bennett Chenene is the latest player to be duped, according to Tshabalala, and the club boss is hoping to ward off any future misunderstandings.
"I do not invite players to trials, that is the role of the technical team and management," Tshabalala told the club's official website.
"We appeal to this dishonest person or people to stop with their scheme and to stop wasting people's time.
"We trust that the law will catch up with these criminals and we apologise to those that have been inconvenienced or conned."
