Not treating the client fairly, AT ALL

My mother and i just called the Vehicle finance, she is the account holder. We spoke to Yvonne Sithole who was Rude, had an attitude and she didn't listen to us for understand. She had an attitude because we were asking her question and because she couldn't answer she resorted have an attitude and kept moving her mouth piece which had a sound. STANDARD IS GIVING US CONTRADICTORY INFORMATION AND NOBODY WANTS TO GIVE US A REASON WHY, BECAUSE THAT IS ACTUALLY LYING. My mother has incurred unnecessary charges for an error of your employees
