Depop have closed my successful selling account for no reason that they can tell me. Many months of faultless sales & happy customers, 100% positive feedback, many hundreds of followers all count for nothing if one of their customer service teams believes you have breached their Tc&Cs - but they won't tell me what I've done, or when. That is if they bother to reply to my messages at all, which they don't.
Bloody shocking customer service.
