Sony — sony bluetooth - mdr xb650bt

Hi, i had registered a complaint with sony product after visiting couple of authorised sony service centre on the issue with the product i purchased.

I ordered a sony bluetooth headphone (Mdr - xb650bt) vis amazon on 21 march 2017. I received the product on 24th march 2017. After months of very minimal usage, i got the to see the product is damaged. My headphone was in broken condition while using it. I would like to clear one more thing.. That the product never fell down, no one else used it and it was in broken status. When initially went to the service centre they told they cannot fix it, because there is no support for physical damage. I went to another service centre and they said the same.
After that, i raised a complaint with sony in their website and after 3 weeks got an initial contact asking for images and invoice. I submitted it within 30 minutes of contact. Never received any contact from the team.

Again, after a month and half another complaint was raised from my end in their website and then got a call contact and submitted the same details as requested first time. I never got any response for more than a month. After multiple contact made from my end over email. I finally got a call from sony to take the headphone to a nearby authorised service centre and they will check the condition of the headphone and will help in buying a new one with a maximum discount of 30%. When i asked why should i buy again where it is your product which is broken fix it and i am ready to pay for it and they replied, no we cannot fix these type of physical damage. I don't understand such worldwide brand product cannot be fixed. The money paid to buy this product is a waste.

I am really unhappy with service provided by sony for there product and need a quick assistance on this.

Apologies for any typo.
