Labor contracts revision to advise on labor dispute

Assalam Alaikom,

I live and work in Iran for 4 years as a storekeeper in est. for food & beverage. I never had any problem, but my company was cutting my salary and did not pay my last 2 salaries until now.

I told them I have family and need my salary but they did not help, and we argued till we reached a bad situation in the relationship. they told me not to come to work anymore and did not pay me anything.

I was shocked that they made a case against me that I had a lot of mistakes and made them loses and they ask me to pay them money now.

Please, tell me what should I do?
