Hp — Chromebook

I had purchased a hp chromebook 2 months back. It was functioning well but there is a problem with screen now and I want to get it repaired. I approached the nearest authorized hp service centre at Poojappura Trivandrum. They denied repairing as they can't repair chromebook. And asked me to call on toll free number[protected] . After calling several times, I could connect with an agent who asked me to contact on[protected]. After trying on this, it asks me to contact on the previous number. I want to get my laptop repaired as early as possible. Please give a solution. Or send an agent who can repair chromebook.
