I selected the Cash on Pick up option when the purchased the item. The 3 star seller changed mind to tranfer payment avoid giving address to collect. Seller Changed trademe terms of the contract How to write feedback to seller? Also deĺete offer from seller i won to unsuccessful?

Seller got my àddress for simplè trade, gave my mobile no reply. Seller reply same email show me proof setup for transfer inside trademe. I guess now feedback.... how to comment to seller and move on?

No legitimate reason , just sudden change of payment to tranfer. I won the offer by clicking paid by cash for payment. This a 3star seller inside trademe. What my next step? Go to trademe dispute?
