[Resolved]  Flipkart — Refund/replacement for defective product

I ordered asus rog 3 on 6th aug from flipkart, i got it delivered by 18aug after opening the package and turning on the phone it's display was defective and only white lines nothing else. So with in 1 hour of delivery i put return request and i got option for refund. On 20th August refund got accepted, even customer care sured that refund will be given . Waiting for day no calls nothing on 26th August they cancelled the request saying it was mistake from their end . After that customer care gave option for replacement not refund we took one day to decide and on other day asked them to replace atleast process return request again on 2nd September they instantly accepted the replacement but again no one came to pickup. On 10th September they cancelled the request again . I am hoping some serious help by flipkart and replace my product soon .
