Kia Northcliff Bad service and product delivery

We were buying Ms Buys her very first car in her name, and were then referred to the Northcliff branch. At first we were interested in purchasing a New Kia Rio, but after some deliberation we decided it would be financially better for Ms Buys to rather buy the Picanto 1.2 but, as was explained to us there were none in stock in South Africa so we settled for the 1leter which didn't have the exact features we liked about the 1.2. We settled with this with exception that we needed the car to be fitted with the SAME BLUETOOTH AS THE 1.2 The extra cost was the included in the finance plan and would be fitted the same day as when she would receive the permanent number plates. The communication from the Northcliff branch came to a end. Ms Buys then sent numerous mails to ask about the number plates, was the bluetooth fitting booked when the contracts would be mailed to her. none of which mails were answered. After several calls were we able to ascertain that the number plates were there. At collection no booking was made for the bluetooth installation and the sales person was too lazy to to find someone to install the number plates. 5 HOURS LATER and the device was the wrong device.
