You can't help me as fast as I need to be helped. It's really as simple conclusion that I don't think Mercari has customer service that are real people that pertain to your problems on their app you keep texting them with your problem in the same answer keeps coming back from them*I sold a white diamond love knot ring to a buyer, my post office was very busy and I had to send out some more items to buyers this one certain buyer I sent her a blue diamond ring that I have up for sale on this app instead of the white diamond love knot ring which is selling less than the blue diamond ring. Well the buyer states that she wants to buy the blue diamond ring that's already on the way to her and she will pay the difference in the app well when I contacted customer service they said I should cancel why am I going to cancel this order when it's already on the way to her it has a tracking number I'm not guaranteed that she's going to return it to me and then I don't get paid if they will change the price to the price of the diamond ring which is selling for $*** and the one she purchased is only $** then I'll be guaranteed my money at least but now no one's answering me because we suggested this to them and all morning they've been answering me right away I don't see what the difference is if the price is changed as long as she gets her item with I get paid this is what my problem is and she's supposed to receive it by today or Monday that's an $*** blue diamond ring that I'm selling for $*** and the ring she bought from me is the white diamond love knot ring which I have up there for $** so she's paid actually $** for the white diamond ring and she said she'll add the difference for the Blue Diamond that's on the way to her
