I bought a redmi4 in june from amazon.. Starting se he phone operate karte karte off ho jata tha kabhi kabhi.. Ab ye off gya and on nahi ho raha h.. Complaint kari mene nearby authorized service centre me unhone pehle toh kha moisturize hai phone andar se tabhi phir baad me liquid damage ki vajah se out of warranty kehkar vapis kar dia.. Kehre hai motherboard damaged hai uske liye apko pay karna padega.. What my query is na mujse physical damage hua na he liquid damage then why would i pay for this major damage.. On the other hand if there would be minor charges mai pay kar deti but its around 6000,... Phone ki cost he 9000 hai phr mai almost 65% kyu pay karu bina meri galti ke.. I want it to get repair atleast
