Pathetic Service @ Hyundai Pinetown

I recently took 2 of my vehicles 2 trade in 4 a new or demo model. 1 vehicle was still under finance the other freehold. The salesperson took the financed vehicle & promised 2 settle it with the bank. The freehold vehicle was with me until I received my newer vehicle. The salesperson kept the financed vehicle & advised that i need not worry 2 pay installment due 2 settlement. Vehicle was kept for 3 wks. Keps msging, calling & whatsapping this guy. He promised 2 sort out on numerous tyms. Never brot new vehicle 4 test drive altho we asked daily. Last call 2 him went 2 Voicemail so I called the dealer only 2 b told that he is on leave & vehicle I was supposed 2 buy was sold. Went 2 dealership 2 sort. They r so busy they really dont don't need my sale that explains y I got treated so bad.... Now the financed vehicle he told me not 2 pay the installment is due.... pathetic service. Called 4 dealer Principal only 2 b told he is in meetings... several times. Spoke 2 other ppl... they say lets move on & try 2 do another deal. Now my financed vehicles battery is problematic... all the petrol, call, wear & year costs... who answers .... no1 cos they don't care...
