Salary not given

Respected sir, we have a serious issue, we were working in company in Mohali, Punjab, from last 7 dec the process was new , at the time of interview they told us that the training period will be for 1-2 weeks and then they said that the material for the training has not been provided to them by the client and afterwards, when the product came they started training. The certification dates changed after every 4-5 days then finally the certification held on 13 jan 2018, we were left pending with our dec salaries. After, giving certification they told us that the result will be announced with two days. The days ever came for the result , everytime they said tomorrow and we were still left with our salaried dues. Then on 18 of jan they gave 35% of the salary to employees saying that if u pass the certification u will get the pending 65% of december. At 30 jan they said to few employees that you have been rejected by the client by giving us no reasons and rest are still left to wait for their result. We are left for jan month's full salary and dec 65% and know they are still saying to wait? we have given our time to them , Please do help us with relevant information so that we can get our salaries.
