If someone says that your poss is useless, do you believe it?

Usually you send text messages. Dear POS users of XXX payment company, your machine will stop using in the near future. In order not to affect your use, please reply to 1 and mail the new POS machine at 202 1 for free, and return to T to unsubscribe. The content of short messages is similar, basically the same words. Generally speaking, your machine is down, and you may not get your account number when you swipe your card. Change their low-rate machine, send it by post for free, use various languages, and use psychological tactics to let you change the machine. I'm telling you, these are pure deception. Never reply to messages. You reply to the message, they call endlessly, and then fool you into changing their low-rate machine. Actually, there are many routines here.
