Employer's maneuvering to escape paying the end of service benefits

I am the only employee in the company and my job included sales, marketing, accounting, administration and delivery.

I worked using my own personal desktop, phone, internet connection and car since the company has not provided any. I started work in this Free Zone company on Dec 1, 2014, under unlimited contract and on my husband's visa.

I have resigned last Dec 11, 2017, and served my 30 days’ notice period last Jan 11, 2018. My employer was supposed to pay the final settlement on my last day but then she re-scheduled to meet on Jan 14, then on January 16 and lastly on Jan 18.

Just before the day of agreed final settlement, she accused me that all my previous work emails have been allegedly deleted. She filed a complaint of Breach of Contract on Jan 18 and I also filed a complaint about her delay in paying my end of service benefits.

She has continuously intimidated me with her plans to file it in court. These false allegations have caused me and my family emotional distress.

Please advise.
