This business does not have a dedicated phone line for fielding customer service issues. When you call the number you are put on hold under the guise that your call will be answered. Every few minute that goes by you estimated wait time goes up. You go from a two minute wait time to ten minutes as per the automated voice that comes on to let you know how much time is left in the wait. Once you have reached 10 minutes the prompt tells you that you have exceeded the wait time and proceeds to hang up on you.Second, my issue is with ordering items and either not receiving them or receiving faulty products.I ordered a suitcase from Mercari and asked the seller to expedite the item. The item was expedited through fedex for Friday 6/22 to come in time for a flight on Sunday 6/24. The item never came, I could not fly out.I asked FedEx about this and they agreed to reimburse me my flight expenses as long as Mercari relinquished all responsibility to them.Mercari does not relinquish responsibilty to FedEx. It is against their policy.I asked for more explanation on this policy. They would not be responsible for the reimbursement, FedEx would be. So I asked for an explanation as to who the policy was protecting because I lost out on my flight.Tim, the FedEx liaision for Mercari promptly closed the case and refused to give an explanation as to why I was losing out on this money.In the past I have either received a faulty item, or nothing at all. I continued to patron this business because I am poor. My flight was to go to an orphanage, I needed the suitcase to bring shoes to barefoot orphans.This is the worst business to patron. They are professional scam artists.
