Salary is on Hold due to performance issue

I was working as a BDM in a Pvt. ltd. of 10 people. Worked for 1st month salary was released, On Second Month Day Started Pressurizing me for Sales which was not being done as per their Expectation. Now at 10th of 3 months They Said, You will get only half of your 2nd months salary and rest will be released once payment form your clients will be coming, and Same will happen this month as well. Till 23rd I requested them to release my full salary of last month as they did not told me about it initially and give me another contract with mix Fixed and Variable component, Which is not there in my Initial contract with company. They Refused and Asked me to leave office Immediately. Now on my follow-up over mail for Salary, They are asking me to Come office and Sign the no dues Have only half salary of 2nd month, No Salary till 23rd of 3rd month. What should I do. .? They sought on me when I go to office, have meeting till 9PM and being girl I fear for such late meetings and arguments. Shall I leave my Pay and move on..?
