Shockingly Bad Tech Support

I'm a long time Dell customer who thankfully never had to use Dell tech support until a few months ago.  Dell has the worst tech support EVER and they actually created problems when taking care of the initial problem with a laptop that was under warantee, a bad motherboard.  Many tech calls (countless hours on the phone), home visits, shipping back the machine, all to repair their mistakes, which, somehow, they didn't notice when they returned it (network card no longer recognized because they knocked it out of slot, reinstalled Windows but didn't register it with Microsoft or give us the code, graphics card issue after they "worked" on it, sending wrong parts to third technician). Seemed impressive at first (they actually come to your home) but it quickly became a nightmare. This was not a one time issue with one bad tech support person, but rather over a period of weeks with multiple people.  Last home tech who came finally fixed the issues and he was wonderful.  The first two home tech people and especially the people at  Dell who worked on it when they asked me to mail it back--MAJOR FAIL!  Much misinformation (two different phone techs told me they had failed to register the operating system after it was repaired and Microsoft wouldn't  let them do it over the phone, but they would send a motherboard with the Microsoft registration code on it and I could enter it and send the motherboard back.  What?  Didn't sound right and the last home tech confirmed the Microsoft code is NEVER on the motherboard (Dell sent two motherboards to the last home tech with instructions to again REPLACE the motherboard, which, at that point, didn't need it.  (We just needed the operating system code, which, of course, wasn't on the parts they sent).  I could go on and on...huge waste of customers' time,  terrible "repairs" and just sloppy, shoddy work.  Pray you never have an issue!
