Maruti Suzuki India — Poor quality products

Recently I have brought igination coil for my swift VXI 2016 from geniune spare parts .
Since in showroom in that particular day They said will take time to look into this job.
So i went outside some car shop for the cylinder 2 error Machanic ask me buy the parts .
I went to geniune spare parts auto nager vijaywada shop.
Even i have the bill too.
But after 2 weeks its the same igination coil has been damaged im getting the same cylinder 2 error.
When i went to maruti showroom we can't so anything since u replace from outside.
Its about 1000 rupees not one rupees. I have send a mail to maruti for some other issues i dint get reply from that.
So I'm making this complaint about bad quality products from Maruti.
