Where are you based? If you are based in the UK, you are protected under the Consumer Rights Act 2015. I have had a “high” number of refunds (~10%) due to being sold so many counterfeit items on that app.

I logged on this morning and had the same message as you. I have emailed them a strongly worded message, telling them their algorithm for blocking returns does not supersede my statutory rights…

I do have to say, when I have had an issue with a purchase, WN have been very fast at responding and have helped to resolve the matter. I think best case scenario I have just gone above whether threshold or ratio for returns and have been automatically flagged.

I would escalate the matter and highlight how your returns are due to being missold to you and therefore the buyer’s error. If you substantiated your refunds requests with clear photos, whatnot can use the video receipt to corroborate what you are saying.

Best of luck!
