I had a terrible experience with Mercari that I feel compelled to share as a warning. The seller used their own shipping label and sent my order to the wrong address—completely different from the one I provided. When I contacted USPS, they confirmed it had been shipped to the incorrect address.I reached out to Mercari for help, expecting they’d assist in resolving the issue. Instead, I was met with the same generic, copy-paste responses over and over again. They basically told me, "The order says delivered, so there's nothing we can do." It was as if no one even bothered to look into my case or verify the information with USPS.Frustrated and out of options, I decided to contact the seller directly. Thankfully, the seller acknowledged the mistake and issued a refund. However, this was entirely due to the seller’s decency—not because of any action Mercari took.Throughout the ordeal, Mercari offered zero assistance. There’s no way to reach an actual person, and their responses felt robotic and dismissive. It was clear they had no interest in helping their customer or taking accountability for the situation.If you’re considering ordering from Mercari, think twice. Their lack of customer support and refusal to resolve clear mistakes is alarming. I was lucky to get my money back, but only because of the seller’s honesty. Mercari itself? Completely unreliable.
