Ekart Logistics — Stole my mobile phone Poco M2

I had ordered a mobile phone through Flipkart with exchange of Poco M2 mobile. Due to product quality, exchange price was reduced and hence we cancelled exchange and kept the new product and paid the differential price.

Delievery guy just confused us and smartly he took away the old device and now he is not picking up the call. We have tried calling him multiple times (atleast 50-60 times but he is not picking up the call) M.No + 91 [protected]

Flipkart also is not responding to us.
