Flipkart — Different Model of IPhone Delivered & Blocked my Flipkart Plus Account

My order id is OD[protected]. I had ordered Apple iphone 11pro 256gb on 13/11/20 but Apple iphone se was delivered to me. i registered a complaint on 28/11/20 with flipkart regarding this asking for replacement or refund. From 28/11/20 to 28/01/20 i.e about two months multiple return requests were raised, rejected and reraised again. The reason for rejection of my requests in those two months were seller denied or didn't accept or logistic team said product was delivered intact or govt id not submitted by me. FYI i had submitted all the required govt ids multiple times to flipkart in those 2 months. Also i had shared pics of product receivec by me and the box in which the product was sent to me.
But suddenly on 28/01/21 My refund request was rejected stating that i had done high number of returns from my flipkart account and also blocked my flipkart plus account. before 28/01/21 flipkart never said or gave this reason.
