Terrible service, I have tried to contact them and I do not receive a response.
It turns out that I bought a laptop with you, which came in handy, but the warranty provided by the laptopo is not one year, but only 7 months, apparently it is because the equipment was activated months ago, so I'm leaving contacting the manufacturer to clarify the situation since Cyberpuerta does not answer me by phone or mail.
