Refusing to provide an employee with a plane ticket due to resignation

Hello!

Good day!

I just want to ask some questions regarding my employer. I resigned from my job as a security guard here in Sharjah. My company is based in Abudhabi Mussafah workers village.

My last day of duty is this coming June 11, 2021. I finished 955 days without taking any vacation from the company.

When I asked about my plane ticket in HR, they refused to give it. According to them, due to my resignation, they are not allowed to provide a ticket at their expense as per the company rule. Is it right?

Thank you!
