Well, he's not a Railway Official. RLWL Quotas are volatile, sometimes they confirm sometimes they don't. Totally depends on GNWL Quota.
He's not responsible for your confusion. Since it's stuck in RLWL you'll get your refund back.
He simply tried to help to the best of his knowledge, show a little gratitude. He didn't deliberately give you false information, you're nobody to him.
Good...
more... luck trying to get help with this attitude.
