HP India — Dim light display issue

I ordered hp pavilion laptop and within 14 days i faced dim light display issue and it was saturday/sunday so i could not connect them.. So on day 16th i called them and raised my complain.. But unfortunately i got no replacement/refund.. HP's customer support is just horrible and their DOA team as well.. My laptop's replacement issue got approved but then DOA letter was about to come.. Engineer's verification was done and DOA letter was issued too.. But then some how it got rejected.. Now its over a month i m getting no response or any update for my laptop's replacement/refund..Every single day i call them and ask about my laptop's update but they as usual ask me to wait for another 24/48 hours for further update but then the result is zero.. And the same thing is going for over a month.. DOA team is so horrible they r just not helping me in my replacement/refund.. Now for how many days more i have to wait for solving my issue? I JUST REGRET BUYING FROM HP AND I SUGGEST EVERYONE OUT THEIR DON'T BUY ANY PRODUCTS FROM HP QUALITY IS HORRIBLE AS WELL CUSTOMER SUPPORT DOA TEAM.. IF I GET MY PROBLEM SOLVED I WILL SURELY GIVE REVIEW. HELPLESS COMPLETELY
