Kia Umhlanga used vehicle division - No ethics

I have been to Kia Umhlanga used car division & had a horrible experience with Ravi the Sales manager & his team. When you think Kia you would think you dealing with a reputable company but they provided me so wrong. I drove out to their dealership on the 12 April 2021 & finalized a deal with Dhasegan for a Toyota Corolla 1.4 D4D but was not asked to put down a deposit as the car was not on the showroom floor as it was send out for detailing & would be returned the next day. Since this was a cash deal we made plans for me to view the vehicle 1st & test drive it before payment could be made. Arrangements was made to bring the car to me on the 13 April 2021 @ 14.30 pm & was also called to confirm the appointment. Dhasegan calls me a couple mins later to tell me another customer has put a deposit on the same vehicle that we had basically done a deal for. So were is the ethics of Kia & their sales staff. Kia you have let a good customer down without any redemption. Your Sales Manager of your used vehicle department Ravi should be held accountable as he handles his sales team & Dhasegan was dealing directly with him.
