Recently, I had to get some information about fire safety. I found the website of a company that provides services, left an application for a callback, but the name was not his own, introduced by Muhammad (I am called Anton, I don't know why)) I was called back, told everything I needed. A few hours later, an unknown number calls me, calls me Muhammad and shakes something about bitcoins, asking where he got my number, he shakes that I allegedly left my data somewhere a year ago and here they call everyone. Yes of course! Called back to that office, made his claims, stunned them, frightened them, apologized for a long time))) This was even the lifehack.)
