Dell representative on Twitter - Riya didn't understand the issue and tried to get rid of me. I contacted them second time hoping different person to pick up it was Riya again but this time she tried to hide her identity and to get rid of me again I asked two times for the name and only then I realized it was Riya again. Very dishonest behavior from Dell. Posted in the forums after a tussle there I was sent to bother a local repair shop. I cant share ticket number because Dell Support don't have support tickets :D but I can share the forums topic: "S3220DGF, not running 120Hz? #19"
