90 days work visa cancellation

Dear friends,
am sibi from India. one month before one Saudi Arabia 90days valid working visa is stamped in my passport by one company in Saudi Arabia. After stamping company told due to some technical reasons the project got delayed and don't come to Saudi Arabia for job. Meanwhile i got another job offer from Saudi Arabia. so i submitted my passport to consulate for 90 days visa cancellation along with previous companies cancellation permission letter. Today i got reply from agent that the request is rejected no reason.

please advice me what i can do further to cancel my 90days visa in a short period

thank you

Try and find out why the request was rejected.  Maybe the permission letter from previous company was not chambered or attested.

thank you for your reply.
in the reply its mention as "without no reason".  the letter is attested and signed.
thanks
