You can go to Human Rights Office and ask advice from them, you can file complains too. Regarding NOC, it's always up to the sponsor if they will give NOC or release. Otherwise you can do this, let your family apply for a family visa for you, find a job again and wait till you finish your 2 years ban after being cancelled by the company. After 2 years you can get work visa without any problems.
