Trai — non cooperation by airtel

My mobile no [protected] & service provider is airtel. Recently i ported my number from airtel vide port no ak234468 which is valid till 26th november, 2017. I am sure airtel will not release me. Because previously i ported my number twice from airtel & the port no were vk419927 & crk55371 respectively. But unable to get release from airtel.
Kindly release my number from airtel.
