Is deducting half the salary considered a breach of the employment contract?

Hi,

I am working with an employer in Dubai since October 1st, 2021. The company is deducting salary in the name of consultancy as I was got hired from India. But there was no such contract between employee&employer for deduction in salaries.

Still, the employer deducted my half the salary for 2 months and I requested to stay at room till the company gets new project also they have taken my educational certificate stating it is the company policy.

I have already emailed the company to pay me a full salary for staying in the room or give me NOC.

1. Can I resign from the company without a notice period as I am in probation period and my contract is limited?

2. What should I do if the company doesn't pay me my salary for the days I am staying in the room?

3. Can this be considered a breach of contract by the employer?
