JOVS customer service
My JOVS device stopped working. I contacted customer services who wanted a video, then another showing more details, I said I'd return it for them to check it but they said to charge it for 3 more hours, which I did but it wouldn't charge any more than four fifths and it still didn't switch on, so they kindly agreed it didn't work and will send a replacement. They replied to my emails promptly meaning the issue was sorted in one day. So although it was a bit of a hassle they were efficient and helpful.
