Mahindra And Mahindra — Warranty not honored for driver side window switch replacement

Address:

Hi,
Recently due to a defective switch I visited the service center for mahindra in hadapsar, pune. Firstly I had to do with a non-functional window and risk theft, when the part was available after several days, warranty was not honored and I was told that it happened due to usage. Not sure if we are not supposed to use the window switch during the warranty period. If this is the post sale response, its very dissappointing. what exactly is covered under warranty?
