Is Beijing Metano Communication Technology Co., Ltd. a regular company? Is it a liar to say that he bought a mobile phone recharge card?

That's a scam. In fact, the lowest recharge card can only get a 97% discount, and that kind of discount card simply cannot exist. The specific method is to let you pay a small deposit first, and then send you a lot of cards, but they can't be recharged, and they will tell you that you need to open them to recharge. But if you fire them, you have to pay the remaining fees, and then let you continue to remit money for various reasons until you have no money or wake up.
