Again come

Dear friends,
I have been working in Saudi Arabia for 2 ago years
and came back to nepal on vacation  visa with noc. I
got another job in Saudi and landed at jeddah
bastana international company within 21 months of vaction . But the
immigration officer denied my entry and deported
back to nepal. My new firm enquired at Ministry of
interior and they simply said that I am blacklisted.
Is there any way to know the reason for blacklisting
either in India or Saudi?
Please help
reply .
