Qresolve Dell Technical support INTERNET

My computers were running very slow so I called who I thought was Dell technician support; it was Qresolve. They told me my computers were riddled with errors and needed to be repaired asap. I regrettably paid them $299 to fix them. They did absolutely nothing but delete a lot of stuff and probably gained access to my personal files. Upon realizing they were not Dell, I asked for a refund but I am still waiting. Like most people who have filed a report, I am put on hold when I call and eventually hang up. Please do not use them, it is a scam. If you do call them, hang up before you give them any personal or credit card info.
