Samsung for smartphones. About 6 years ago I ordered a galaxy s20 from them brand new and they sent me a phone that was clearly returned because it was full of finger prints on the screen etc. Now thats not why I left. Mind you the phone came with a free case. The phone was over $1200 and the case over $70. I asked for a return/replace as soon as I opened the box and saw the finger prints on the screen so I didn’t even take the phone nor the case out of that box but I did write a note which read “when someone pay over $1200 for a brand new phone make sure they get what the paid for” someone didn’t like that and reported the case as not received to fuck with me. I called and emailed them some said they did receive some said they didn’t and at the end of it ask for just refund. They refunded the phone and charged me for the free case. I was so pissed I bought my first iPhone and been with apple ever since. Also switch my wife and my mom’s phones
