Hyundai Motor India — 170907 hyundai creta, stepney wheel

Dear sir,
I bough one hyundai creta sx+ diesel 1.6 suv from popular hyundai, kochi. By last week.
I would like to highlight you that, i received car's stepney wheel is not as per other 4 wheels (Diamond cut alloy wheel)!!!
Why you are not providing alloy wheel for stepney??
Others all are providing (Ford. Toyota, honda etc.. Etc..) stepney same as other wheels? Why you can't.
Even in gulf, hyundai is providing alloy wheel for stepney too.
Either you need to have clearly given in your manual or delayers should be explained since buying.. (See attached manual with key features.)
I already been complaint hyundai, kochi. But still not get any proper answer yet.
