Another DMD 6000 home laser rip-off

From a reader:

Andrea congratulations for your website. My name is Pablo I am from Spain and I am another victim of Global Electrolysis Supply I lost 4200$ in DMD6000 lp a diode laser machine that is useless. This company is a SCAM, I didn’t send back the machine for the refund because I didn’t trust them and because I am too far. I don’t know what can I do to prevent people from buying their products. Please tell me what can I do. Thank you.
