Maruti Suzuki India — tyres keep damaging

I have brought a wagonr car on december 2012. Total kilometers used less than 30, 000. I was forced to change the car tyres 3 times because of tyre outside wear. So many times we check the alignments and service centre says all fine. We raised the complaint at the third service. I live in uk. My mother is using the car. Everytime we make a complaint, the company arrange a wheel alignment test and thats it from them.
I really would like to make this again to your attention by saying that there is some manufacturing defect. Please do the needful. We are so upset by changing the tyres frequently without much miles on the road.
