Rejecting a legally submitted resignation of an employee

Dear Sir,

My name is S. Mohamed Raazith.

I have been working in Abu Dhabi for the past 1 year and 7 months, my visa is on an unlimited contract and my notice period is 1 month.

I got another offer from a company which is also in Abu Dhabi. I submitted my resignation on September 4, 2018.

Now, my company is saying that I need to wait until a replacement comes or complete the contract and go like that.

If I go to the Indian Consulate in Abu Dhabi, will they help? I need to join my new company as soon as possible.

Please advise me.
