Samsung — Product display has gone within 10 months of mobile purchase..

Address:

srinivasa steel and homeneeds opposite of gentle man kaman bazar, kaman bazar road

I have taken samsung S9 plus from flipkart and TRUECOMRETAIL is the seller..
i have trusted and took the mobile...now it gone to the worst...as i never expected.. from Samsung
all my display was gone and to take the new display its charging around 20, 000...as we can buy the new mobile also..i think.

i have purchased the mobile exactly last year..and this problem in my phone is occuring from 1month..
i have gone to local showroom they told no problem it was fine..but now they told that display gone it charges 20, 000...
