Poor Service at Nissan Middelburg

My car was recalled for a safety defect on air bag,after that my car and engine was washed and this related to my plug coils being soaked,ever since then i have problems with coils that are now starting to fail,i did take my car back but they removed the water,i already replaced one coil on my own cost and had dianostics done and indicates another coil is shorting out,Nissan Middelburg fails to take responsibilities for their actions and to pay for the damages
