Amazon - paid for the order but product not received

I had order a phone (Nothing phone *- ***GB) from amazon on *th March. and it was estimated to be delivered by **th march. Suddenly on *th march. the product is showed as delivered, while in product tracking it was showing ' delivered in Bangalore while my location is in Thane, Maharashtra. had not received the product so I raised a complaint to amazon, they said it might tagged incorrectly as deliver. we will investigate and update you. I was following up but was not getting any update so I raised social escalation through twitter about the incident. the social media team, of amazon contacted me said they will investigate the issue. after multiple follow-up they informed me that your product has been delivered to you in intact condition. I asked them it is incorrect I have not received the product , the tracking shows it delivered to incorrect address and I haven't received any communication through email/text about the delivery. while asked for more details such as to whom it was delivery and to what address it was delivered they denied to tell any information. i called amazon customer care multiple times, they said they cannot help me the issue is resolved by the social media team and denied to tell me more details. This is clearly fraud.
