Worst company for any graphic designer or devloper - Senior Graphic Designer ENT Netwrk Employee Review

i worked in this company for 2 years as graphic/ui designer and i know how this app works. Salary is always paid on the last days of the month and sometimes they withhold your pay for some nonsense reason . I haven't received my experience letter and joining letter even after saying lots of time. If you work in this company (please never make this mistake) then you have to give them 5 star review and also share the app.. working for them is the biggest mistake of my life. I lost my personal laptop. and precious time of my life. They just want free interns for their work
