Is it reliable to accept Feng Ke's orders? com？

Before signing the contract, the salesman was very active and his promise was very pleasant. After signing the contract, the salesman quit the group directly, without after-sales, and everything promised was not fulfilled. Speaking of cancellation, the so-called customer service is cold, and the fee will be refunded after three months. I really don't think the contract can be terminated smoothly after three months, and I don't think this company is simply a liar company. I hope my colleagues who are investigating this company will not be credulous.
