Tata Motors — inappropriate replacement wheel given...

I purchased the top variant of nexon petrol model (Xz+) and was utterly disappointed to notice that the stepney was not the same as other wheels which are cut diamond alloy type. But was instead the iron wheel. When i spoke to tata motors they said it was their policy and not much can be done about it. I have brought it to their notice that it meant extra time and efforts for the customer to replace the wheel twice as i can't drive my vehicle on two different kind of wheels. And at least for the top variant they should consider giving an alloy wheel as the stepney. It's been a while that i have taken up the matter with them and there has been no resolution so far to my problem. Please look into this.
