Handing incorrect info to clients

On the 18th April I visited the car find show at Bright Water Commons, I met a sales representative called Fanie from Hyundai Constantia and he made a good deal with me to purchase the I20 demo model at R104 000, we went ahead with the app and the finance was approved but we awaited several days for feedback on the arrival of the car, only to find out that Fanie handed us the incorrect info and it was an I10 not a I20 for the price quoted, at this point in time I decided I don't want an I10 so I asked him to make a plan and to this day nothing, then on the 8th of May Ziska contacted me and advised she has a Yaris for me, I asked her to reserve the car for me I def. want it but have no time in the week I will come on Sat the 13th May, she then goes and sell the car before the Sat, I still await the manager to call me back, he tried twice but the call cut but he never worried to call back, this is the type of treatment I got from this branch and to date they have not made a plan to compensate me, I clearly asked them to keep the 2nd car for me but they just ignored my request. They are *********** and refuse to help people even though we willing to give them the business.
