WORST SERVICE EVER!!! NO FEEDBACK / SATISFACT!!!!

WE BOUGHT A FORD RANGER FROM KIA MENLYN IN OCTOBER 2015. FIRST OF ALL OUR TRADE IN CAR WAS SETTLED LATE, SO WE STILL PAID AN INSTALMENT ON A CAR WE DIDN'T HAVE ANYMORE. WE HAVE HAD PROBLEMS WITH THE AIRBAG LIGHT OF THE NEW CAR SINCE DAY ONE, WHICH WE REQUESTED TO BE FIXED BY FORD. KIA MENLYN TOOK THE CAR TO THEIR OWN \CONTACT"TWICE NOW AND THE AIRBAG LIGHT IS STILL ON. WHAT IF I DRIVE AND THE AIRBAG COMES OUT AND I MAKE AN ACCIDENT??? WE ALSO STRUGGLED WITH THE KEY OF THE NEW CAR"
