Did Chery fail in CET-4?

Today, a 985/2 1 1 Grade 02 fresh graduate of a key university posted such a post on the Internet. Last semester, I signed an employment agreement with Chery Automobile Company. At that time, I asked the company to recruit the person in charge of our school, and did he ask for Band 4? He made it clear that he could not, but he required a diploma and a degree certificate. As we all know, if I pass CET-4, I can also get the above two certificates. Although I have heard many senior brothers say that this company's reputation is extremely poor before, what I never expected was that the company suddenly called me today and said that it had not passed the national level 4. According to the additional terms and relevant documents when signing the agreement at that time, my agreement was invalid. It's only over a month before graduation. What should I do? I believe there should be victims like me in universities. You can imagine how much loss the company's despicable behavior has brought us. As a well-known company, it is understandable to terminate the agreement for its own development, but whether it should be aboveboard. Whether the means should not be so despicable. Is the additional clause of the relevant certificate a reason?
