Is Mother Donkey trustworthy?

I don’t believe it, let me tell you about the tickets I bought on that! ~ I made a reservation on August 13th for the Happy Valley tickets for August 14th, plus Golden Face Dynasty tickets, which cost 250 yuan each. At that time, I bought four tickets through Meituan Group Buying, which cost 1,000 yuan. ,~~ Then I went there on August 14th to exchange my ticket at the Happy Valley Group Purchase Office. I asked the Happy Valley service staff to check the text messages on my mobile phone. They told me that my order had been used, which was strange. How come I have used it if I haven't entered it at all? Then I called Lvmama.com for manual service. They said that my order had indeed been used and they wanted to review it for me. Then they told me to apply for a refund, and then I applied for a refund. So far, It has been four days. I just called them and they said that my order has been used and they asked me to wait for another three working days. I wanted to say, what is this? I spent so much money, but it didn't work out, and I had to keep the money with them for so long. Now they tell me that it's under review, and they don't know if the refund will be successful or not, alas. I'll just accept my defeat and learn from it. I advise you not to buy travel tickets online to avoid being scammed! ~
