Time frame for paying EOSB and visa cancellation

How long must we wait for our End Of Service Benefits and cancelling of visa, and for the company to issue the flight ticket home?

We received letters of 30 days' notice of termination of the contract. The contract ended on 18 October 2018.

The company let us sign a letter of unpaid leave in case more work is received. We requested to leave the UAE.

We are still waiting for our EOSB on unpaid days. We have company accommodation but no monies for living expenses.

What must we do?
