Amazon India — Wrong Item Sent & Harassment in Return

I ordered a mobile phone (Samsung Galaxy M33 5G) price 18999 from Amazon India on the 9th Aug and a different mobile phone (Samsung Galaxy M13) was delivered to me on the 15th of August. When I raise this issue they did an investigation and on 20th Aug they told me that I can replace the mobile. The next day a delivery guy came to pick up the wrong item but he did not pick it up as in the original order slip it was written as Samsung Galaxy M33. After this same scenario happened for 4 consecutive days. Amazon is unable to resolve this issue also they don't have any knowledge of how to deal with it. I don't know whether the wrong item that was delivered will be returned or not. Please help me with this. This may happen to many other customers.
