Is Huaxin Zhongan Security Company formal or informal?

It's not formal at all. When I went, I said it was 2400 yuan a month, then I worked for 8 hours, and then I deducted the clothing deposit of 100 yuan and took your ID card. I said I would give it to you in a few days, and then I will send you to another place, saying that I will be on duty for 3 4 days. However, when I got there, I didn't go back for 3 4 days. I stayed until you finished two months, and finally gave 3000 yuan. Then ask to leave a card number and say that it will be given within 65438+
