If the merchant / seller is not cooperating to resolve your complaint, or provide a refund, please contact support@tradebit.com. Include a copy of your most recent communication with the merchant / seller. Be sure to state clearly that you already contacted the merhcant / seller and they are not helping to resolve your complaint.
Important: Do not open a paypal dispute right away. This is the slowest option for receiving a refund. Contact the merchant / seller first. If there is no reply, or the seller is not cooperating, then contact support@tradebit.com. Paypal disputes will cause a delay and could result in the seller blocking you from future purchases.
