I had a very disappointing experience with your service. I ordered two pairs of shoes and requested an exchange for a smaller size. After returning them, I received a message stating that the quality check (QC) was unsuccessful, without any clear explanation. When I contacted customer support, I was told that the tags had been removed. I was then informed that the items would be sent back to me, but I am still waiting. I followed up again to ask for an update, but received no response. Now, another representative has given a completely different reason, stating that the serial number was incorrect. It is frustrating to receive inconsistent explanations from different representatives each time I reach out.
