The responsibility of meituan to book hotels and cancel orders and how to claim compensation?

Bullshit compensation, Meituan's customer service was very tough, wrangling with each other, shielding each other, and finally forcibly hung up on me, looking like a love answer. Ask him who I can talk to if you can't solve it, and he will directly answer that no one can help you solve it, that's all. Anyway, you can't do anything about the Meituan, just a man.
