Vivo Mobile India — Green line on multiple handset I own of same company vivo.

Address:

H6/19,burma road Burmamines jamshedpur

With no physical damage on my vivo x50 phone it got green lines every where in my phones display now after using for 1.5 years the company ask me to pay around 10000 rupees to fix it. Which is there software glitch. After buying a phone for 40000 using it 1.5 years and now they just ask 10000 rupees for the problem which may be created by vivo to just loot the hard earned money. Similar case with one plus phones also but they accepted there fault and replaced the screen for free of cost ether the phone is under warrenty or out of warrenty. Pls help i have 3 phones of vivo and all three phones have same issue of green lines on screen bow is it possible.
