Bought computer for work last year May 2018. Hard drive seems to disconnect randomly around September 2018 techs couldn't find any issue, fine, happened more frequently later so called back this year March 2019, got an error code, stating drive is a failure, the rep tells me an onsite tech will come replace it for me, booked two days out for the appointment, great, on the day of the appointment I confirmed with someone in an online chat that I would be called when he is on his way....waited till the end of the night, no show, no messages, next morning I called in and inquired why the tech didn't show up, this rep finally tells me the tech would have received the part but was supposed to call me to confirm a day to swap it out.... worst tech support ever, would have been faster if they shipped it to me and I swapped it out myself then I wouldn't have taken a day off for bs.
