How about the dietitian certificate of Beijing Minhang Education Consulting Co., Ltd.?

Hello, let me help you solve the problem. I hope I can help you. I cheated you into the pit with various discounts and group purchase prices. Later, in order to reassure people, I even said that I could pay a deposit before paying. I actually chose to send you some information and sign a contract that is beneficial to them. Before paying the fee, I will always say that we don't have a second charge, and then I will ask you to increase the money to upgrade the package with the changes of national policies or related policies. If you don't upgrade, you need to pay extra. If you want a refund, I'm sorry to see the contract you signed. Even if you are dissatisfied with their extra charges and even want to refund the money, they have no relevant obligations. Contracts are all favorable terms for them (the obligations they need to undertake are particularly simple and the constraints are quite few). If you keep pestering, they will leave you alone. This is the training institution for sensitive education and garbage. I sincerely hope that my answer can help you, and I wish you a happy day!
