Traumatic Driving Experience with New Hyundai Santro released in 2018

I purchased the new Hyundai Santro Sportz cng model in Dec 2018, 3 weeks ago which I've driven about 750kms - Even being the top model in the segment, the cost cutting in the car has really made my driving experience traumatic for the below mentioned reasons to the point where I have started getting jittery about getting behind the wheel - a) Since the steering is permanently adjusted in a lower position I am unable to get in or out of the vehicle easily. Every time I get in it seems like a herculean task (being heavy build at 5'10) I hate to get in. Moreover since I'm unable to adjust the steering wheel or even change the height of the seat I keep driving while my back and thighs get sore from driving. After driving from Pune to Panchgani (220kms) I almost had to take 15 pitstops as I kept suffering from pain. This clearly is a design defect due to huge cost cutting initiatives. b) The placement of the power window panel in the middle has made me almost crash into another vehicle twice because all the 4 windows are placed together and most times I've actually opened the rear window instead my window while driving. c) Being an avid fan of Hyundai India, I was a proud owner of the old Santro Zing, then the eon and now the new Santro and can tell you that this new Santro is by far the worst vehicle I've ever driven. Initially I assumed that I'd get used to the new driving arrangement, but now I just feel like returning this vehicle back to Hyundai. c) The cng tank is amazingly smaller that almost any cng tank fitted in other vehicles, with the capacity of only 8kgs I've got to get refuelled perpetually every day as I run out of gas (average being as low as 15kms on cng) and lack of availability of cng everywhere makes me not want to drive the car around as one I'd have to hunt down a cng pump for about 10 Kms then wait in the line for more than 20 minutes and then repeat this every 2nd day I go to work because the tank size is so small. I request Hyundai Motor India Limited to please take this vehicle back and refund my money, vehicle registration number - MH12 XX XXXX
