Bad quality products and no after service

I have ordered the bonnet protector and window shield for my JAC T9. The bonnet procter when fittes was warped and after indicating to them, they suggest by heating it up to reduce the warpage. On the window shield when putting it on the vehickle there is a huge gap and seems like the product is not made for the vehicle. After communication they did not even reply back. This is not products that must be supp**** to customers and not to be used.
