The training fee of Shenzhen Silly Sister Home Economics Company is very high. Can I get a refund if I regret it?

My friend paid a training fee of 5,060 yuan on May 5th and returned it on the 9th. Only 1.5 days of training was given, but they only agreed to return 2080 yuan, and 2980 yuan will not be returned even if it is killed. My friend would rather let them deduct the upfront expenses, such as meals and accommodation. They can't feel the cold like dead mice. Because they are engaged in legal sideline, which belongs to economic disputes, call the police. You can only go to court to sue, but a few people can afford it. They are just cheating money in this society. Other methods are useless. On the first day I arrived at the company, I tricked you into signing the contract and didn't give you a receipt, but the stamp was not from the silly sister housekeeping company. As long as you pay the money, someone will tell you to learn this and that right away. The company's food is poor, and the dormitory is also very poor, which is different from pyramid schemes. The fellow villager lied to the fellow villager, and shooting at the back was not negotiable. If you really want your money back, you can only have the cheek to sit in her company every day and call people in to be careful of being cheated. Baidu, it is not too late to pay now. Moreover, the certificate issued by their company belongs to internal training and is not recognized by the state. I hope you can tell your relatives and friends in time to avoid being cheated again. It is really spending money to buy gas. God loves you, and I hope everyone present.
