There is an epidemic of fraud in Russia.
“High technology.” So SMS come "from a friend" with a request to fill up the account, then "admin asky" threatens to block the number, if you do not send a message. In general, the people have already learned these tricks and do not give in to provocations. Individuals meet...
My friend works in a call center of a cellular operator. He told such a story recently. From the first person.

The call. A young woman, judging by her voice. She says, so and so, there was a message – allegedly she won the plasma panel in the “number draw”.
To get the prize, you just have to send a SMS with a specific code to the short number XXXX, and in response, supposedly, will tell you where to go for the prize.
Aunt doubted and called the operator.
I politely and extremely detailedly explained to her that they were fraudsters, that we had no joke, rejoicing in the soul that not all of us are still losing their heads when we see the hole. He warned that for such a SMS a considerable amount of money would disappear from her account. Tom said goodbye.
After a couple of hours, a woman aged forty-five or fifty goes into the office, all in angry emotions, and suddenly begins to scream that she just had money on her account, a whole of four hundred rubles, and now she owes a hundred, that it is fraud on our part, that she will not leave it, well, and so on. Have you done a detail and what would you think? The same person who called and to whom I explained everything to the Russians in white, took and sent an angry message with threats to the “dirty fraudsters.” The shortest number. To be loyal and to duplicate. No, if a man is bad in his soul, it is useless to teach him.
P.S Free advice from my friend – if your wife is blonde, don’t put a lot of money on her phone, better more often, but little by little replenish the balance.
