I ordered the POCO M4 Pro 6GB/128GB variant from Flipkart on 10th Aug 2022.
this is the order id: OD[protected]
and they sent me a 6GB/64GB variant in the box. I was not at home when they delivered my order they left it to my family member and when I returned back then I noticed they sent me the wrong item. Now I am calling support to send me the correct variant but they are not replying to my call and removed the return option from my Flipkart account.
Please help me.
I got scammed by Flipkart.
I have full unboxing video evidence also.
and they can match by IMEI no. also that which model they sent to me and what I ordered.
Please help me soon.
