I have very good reasons to assume that the company platinumaccountgroup is nothing more than a boiler room. They try to promote the company LAZARAGA. A mining company.
They work exactly like the company Talbot and Reese, which contacted me a couple of years ago, which is now a confirmed boiler room. These people call you, very scripted intro, try to find out how much money you normally invest, ask questions about your personal life, and close the conversation with "remember person X really good", he'll call you once we have good news. And also, "remember company X really good". A few days later you get another call, the guy who's name you had to remember, and apparently they have an upcoming IPO or other inside information, and before you know it, you have to send money accross to another completely unrelated company. Shortly after that, you don't hear them at all anymore. I lost 10k euro with a company called ATM Capital last year like that.
They all use vague websites, no pictures of real buildings or offices WITH their logo, just a general jpeg that you can find everywhere online. No registration numbers, no vat, when you call them it's an answering machine, and when they call back it's always a private number.
If they contact you, play along, then give as much details to you locale police office, FBI, Griffin and Miller, don't just leave it for what it is, or they will make new victims. Elderly or people who want a boost in life, but will only be disappointed. Families get torn up, husbands and wives divorce, people even kill themselves. They couldn't care less, as long as they can continue their lavish life style.
