The first 3 things (10 minutes)

  1. Photograph the defect and screenshot the listing, inspection record and payment history before any repair.
  2. Tell the seller what is wrong and what you want (refund, repair, exchange) in writing and keep the reply.
  3. If you paid by card or payment app, ask the provider whether the payment can be cancelled or disputed.
