What a liar. I bought a Erjian bet from them this year, totaling 4k yuan. It didn't work at all. I signed the agreement and said it was a refund. As a result, the customer service is all unreasonable. Although there was no swearing at that time, I hope everyone will prepare well for the exam. Don't cram for these swindlers and let them be cheated. I also hope that everyone will come out together to report such a liar.
