If I could give minus stars I would I purchased a pair of wireless sport/running headphones for my husband for Christmas. Due to us both getting covid they remained unused until he felt better but we were initially also unsure as to whether they were charging properly but decided to test this a couple of times before getting in touch with Samsung thinking we were doing due diligence and being reasonable. It turned out there was a problem as they wouldn't hold charge and the battery would drain while turned off. Unfortunately by the time we had decided for sure they didn't work properly it was day 22 since purchasing, taking us out of the 21 day returns policy (which is an absolutely immoral period for electronics and not clearly mentioned when purchasing) When I contacted customer services the first response was 'Well if you knew they were broken why did you not return them within 21 days' I was then passed from rude accusatory chav to other rude chavs, back a forth for days, I got passed around and told to call different numbers, who told me to call different numbers. The process was so mind damagingly frustrating I thought I'd just give up and let them keep my £100 so I could piece my head back together I ended up getting in touch with AKG who offered to look at the headphones, confirmed they did not work so sent out a replacement. So in the end another company helped me out
