Bosch Home India — Front door not working properly

Address:

B-3/39,Sector-16, Rohini, Delhi-110089

I purchased Bausch Wasing machine 8kg Front Load machine though Amazon, Order ID[protected].
Since then its front window is not working properly. I have already filed three complaints and your technicians have visited us but they are tring to convince us that it is ok. Secondly that it is a plastic door aand if it needs replacement we will have to pay for it.
It is some pre existing problem for which I may not be responsible. If the door is not repaired/replaced to my satisfaction, I will file some complaint for compensation with compensation for mental harrasment.
