I've had my Dell Optiplex 9020 since early June and have been very happy with it. I had a problem with the DVD player (would not open).  I called TekRefurbs & was talking with a friendly human being. He had me check a couple of things. He determined it was broken & would ship me a replacement within 48 hrs.  Received the replacement well within 48 hrs.  Again I called TekRefurbs for tech assist & was Talking to a very friendly rep. He was very helpful & solved my problem.  Can't say enough about their support!
