Need help with my dell Inspiron 7558 case

Hi,

I'm looking for Dell US customer service email address as I had bought the new laptop Dell inspiron 7558 having service tag from dell US in march 2016 and after that i moved to india. After 2 months of usage my laptop screen started showing vertical lines.I contacted dell customer care india and they took more than 2 months to repair it. I'm highly dissatisfied.I want to reach out to the Dell US Customer Care for my issue.Please help me with it

Regards
