Hi, my name is Rodrigo, I am from Argentina.**I've this issue with XFX (www.xfxforce.com)**I purchased two Radeon RX-*** in **** (RX-***P*SFG*) and mouths ago began some technical problems with both (I used in crossfire), they stuck the system with no response, sometimes blackscreen and blocking USB ports and some grids pixelation errors to. After a lot of tests (incluiding testing differents versions of drivers, SO, hardware, PSU, etc.,etc..) I decided to contact XFX and open a ticket because this brand manages like this, first you registred your product, them you request a technical support ticket, and finally is other things are exhausted you ask a RMA.*After began the process XFX does not respond in the internal chat, they dont have email to contact and no response in phone contact ((***) *** ****)* they DISAPPEAR.*I opened the ticket last july and its n* T**********, figure as "pending".**I would like this to resolve with a complete RMA.**Thanks in advance
