Amazon India — Fraudulent activities by amazon customer service and investigation staff and delivery carrier

Address:

India

I ordered a mobile phone iqoo z6 ₹14599 prepaid from Amazon app on 28th june and on 30th june it is showing as delivered. Order#[protected] . So i went to the delivery office and they said that all the parcels with otp varification got cancelled. So i called amazon customer service they told me to wait for one day as the delivery can be done in 24hours even after showing as delivered. Didnt receive it still. After that i called them again to register the complaint and they registered it and told me to wait for 5 days so that the investigation team can investigate. After 5 days i called them again to know the status of the investigation.. they told that our investigation is completed and we couldn't file a refund or return on your order as our investigation is showing that you recieved your product. So they told me they cant help me anymore regarding this and hung up the phone. And i was not even in the city that day. I didn't recieve any otp so how can the product be delivered without providing any otp. My sister saved money for 5 years for a mobile phone and she gave me the money to order that for her. I am a patient of hypertension and severe depression and this is extremely affecting my mental health please help me These type of fraudsters must be punished strictly
