Maruti Suzuki Motors - Price hiked huge of 32 after booking

I booked WagonR by last month (**th Jan), however the hike of **.*k for an entry level vehicle announced later by end of the month. The company billed the hiked the price for the booking made as well. I'm really not sure, what's the meaning of booking here. Also is this really logical, ethical..? The company never responded for any of my queries till today.

*. Is this really make sense to raise huge (**.*k) for the entry level vehicle .? by considering only middle and lower middle class people generally go for entry level. I personally never seen this much hike in the past.

*. If it is a huge increase also, I hope there are options with company to make it lower for the booking already been made.

*. Moreover the price hike for the existing booking is looks to be logical thing compare to any other product in the world..? I think competitors like TATA and Hyundai realize it is something not ethical in an industry.

*. Being ethical and following principles of the company does it really take **+ days to reply to any customer email irrespective of follow-ups.?

*. Being a customer do we have to struggle this much to reach out someone in Maruti..?

I decided that it is not possible reach any of the representative at Maruti as they do not respond when it comes to them as an issue, they leave it to dealer only.
