My company did not give my gratuity

The company must pay the worker the following amounts:
- End of service gratuity, which is calculated by twenty one days' salary for each service year from the first five years and a month's salary for each year that exceeds that.
- The end of service gratuity is calculated on the last basic salary after excluding all allowances, such as a child education allowance.
- Paying a cash allowance for annual leave that the worker has not received.
- Flight ticket.
If the employer refuses to pay  the end-of-service gratuity, the worker can file a complaint with the Ministry of Human Incoming and resettlement against the employer in order to obtain his rights
