Bose India — Noise cancellation issue

Address:

Jewel Square Mall, Koregaon Park

I bought my Bose NC700 (Rs 34, 500) on 22 Feb 2020, everything was working fine untill the day I installed the Bose Music App on 4 Jan, 2021. I connected the Headphone and the Firmware got updated by itself. After the Firmware update, the Noise Cancellation feature completely changed. The noise which wasn't audible before the update was clearly audible after the update.

I've lost the receipt, I called the store i bought my headphone from on 25 Jan, 2021 to ask if they can give me a copy, the store told me the product Serial Number was enough and no receipt was needed for servicing. Also i was told the service centre was relocating to Koregaon Park, which was close to my residence from 1 Feb, 2021 and I could just go to new service centre without any appointment.

I went to the service centre on 1 Feb, 2021, where the technician present check the device and told me that the Noice cancellation function was working. (My response - Not as effective as when I bought or before automatic firmware update). I told him I wanted the firmware to be reversed to the version when I bought the device. His response - we just relocated today, we'll be functional from 15 Feb, 2021 onward. I was told I could drop off the device by 15 Feb and pick up after 3 days.

I went back to the service centre on 15 Feb, to my surprise I was told the service centre will not be functional before the end of the month (i.e. February) also I can't just walk in and that I have to book an appointment before visiting the service centre (which he never mentioned when I went on 1st Feb) and come back after 1 March, 2021.

The problem is the one year warranty provided provided by Bose ends on 21 Feb, 2021. The service centre is not functional till then. The Bose Customer Care Number (website[protected]No response) and (provided from the Bose shop[protected]Call unable to get through)

I don't know how much the service centre will charge to fix my headphone which is out of warranty. I want the company (Bose) to take responsibility and repair my device without any charges when the service centre officially become operational.
