Can a Company Freeze Your PPF if You Resign Without Notice? What You Need to Know About Claiming Your PPF Money

If an employee resigns from any company without serving the notice period, can the company freeze the PPF account? Can the employee claim the money deposited in the employee's PPF account?

For any PPF account, after how many years can an employee ask for the refund of the PPF money accumulated in the employee's PPF account?

PPF account is not controlled by the company. I presume you must be talking about EPF. The company cannot touch money lying in the EPF account. It is protected by law, and even a court will not be able to attach money in the EPF account.
