Is the low-cost mobile recharge group purchase in Meituan.com credible?

This is the case with the US Mission. 10086 may not know it, but it should be cooperated by other channels. I think the following introduction is about the method of refunding telephone charges, which should be adopted. If Meituan dares to buy a group on the website, it will definitely not be fake. Such a big group buying website will not cheat consumers casually.
