[Resolved]  Amazon India — LG W31+ : Hanging issue : Not accepting return

The device got delivered on 9th October, and the device having issue of hanging and lagging since very first day. Initially I thought may be after updates it will be ok. but still having issue so tried to log complaint on 13 or 14th October 2021, the amazon web site provided a link to download some self check app, the app confirmed the device having no such kind of issue. but my problem not resolved so tried to each out to customer help center yesterday 20-Oct-2021, the executive told me there are no any technical team available so call in the morning after 8:00AM so I called today 21-Oct-2021, the executive denied to for help and returning or replacing this device. I know they records customer activity on their web site and they sends suggestion or recently viewed products. my also should be there but they are not accepting it.
Please help me out from this problem and help to return this product to amazon.in
Thanks
