My customers are being asked to invest more money with an unlicensed advisor.

One of my customers told me they're investing money with a financial advisor down in Laredo, Texas. The website is schwab-dm.com. The company is called C.S. Diana Martinez, LLC, and it used to be called Charles Schwab Diana Martinez, LLC. The address they have is 104 Del Court suite 100, Laredo, TX 78041, and the phone is 956-324-1903.

This person, Diana Martinez, is guaranteeing returns on the money invested. My customer already gave her cash, and she's been giving them checks for the so-called returns. They think she's legitimate, but to me this has every red flag of a scam or a Ponzi scheme. I checked, and there are no licenses under her name.

She's claiming to be a financial advisor, and now my customers are wanting to give her even more money. It doesn't feel right at all.
