Amazon India — Return of laptop

Address:

II e, 255b, sector-2, kamana vaishali, ghaziabad, uttar pradesh -201010

I have ordered a laptop on 10.05.2021 and the ordered placed was defective when received and when I placed return request the amazon executive came and took away the laptop but nothing got updated on the app from which i have ordered which is amazon app.
Now when I asked your executive they say that nothing was picked up from their end and only me and the amazon knew about the replacement.
If the person came was not from amazon then it was a leak from amazon employee/executive and it is breach of cunsumer privacy.
kindly take up the matter and initaite refund.
