Redmi 3s prime. Review on Xiaomi Redmi 3S Prime

Most pathetic phone I have ever seen.May b some people have received nom defective phone bt have got defective one.Okay, its normal but there is most valuable thing in this world called "time".To sort out this replacement issue I have wasted my 15 days now.My phone is not showing VoLTE sign and it's though VoLTE supported phone I can't have that feature. Initially Flipkart executives mislead me by saying download jio app and then you vl b able to call . But y should I pay for data after 31st December as I have volte supported phone bt vd d defect.Then they put my number on block list.I was not able to call them from registered number, everytime d number was not available .So I had to call from my friend's number and again I had to follow d while procedure and now they r saying they can't give refund.Actully I should sue Flipkart on court for mental harassment but I am only asking for my hard earned money .Coz I wanted that phone to present my fiance on 13th Oct which was her birthday.As I gifted her defective phone she was upset with me.Then I had to buy another phone in rush.So now replacement of this phone has no use for me.Its most horrible experience oli ever had online.They say it's "big billion day" bt they handover you defective products.
