How to cancel my order? What should a buyer do when a seller wants to cancel an order? How do I open a dispute? After the buyer initiates a dispute, how long does it take for the U7BUY Team to solve it? How can I contact the seller? Should I click Confirm Receipt before receiving my purchase? The seller did not complete within the promised time, what do I do? I have not received the item but the status shows that the seller has completed it.
