Didn't get salary of last month - Senior IOS Developer Chawtech Solutions Employee Review

After working there for one year the workplace culture was good, but when you wanted to leave, HR showed its true face to you. When you join, they want you to join the same day, and when you want to leave, they ask you to serve 2 months notice, all without informing you at the time you join. The most important point is that these guys won't pay you your last month's salary and will never give you experience. HR has a terrible attitude and can't see you growing in your career. My salary for the last month hasn't arrived yet. I have contacted them repeatedly, but they never reply.
