Something similar has happened to me after many positive experiences. My account is now "restricted." This would not be so bad if they just restricted my ability to purchase. But in fact, they are restricting the ability to write them on customer service issues!

I had the exact same thing happen to me. I joined Wish in June and have been buying consistently with them until Oct 4. When I tried to place an order, I got a message telling me that the card I was using was fraud. I wrote to them and they asked me for proof that the card was mine... I sent them screen shots of my bank statement. I can't seem to get my account unblocked. There's no phone number to call and each time I email, they read it, and reply and mark my email as "solved" when it's not solved.

I bought a $10 item that was a piece of junk so I wrote them. It said they would get back to me in 2 to 3 business days and that was 3 weeks ago and I'm still waiting. I'm going to throw the piece of junk away and post on Face Book that they sell junk and don't follow up on things. I think that fraud thing that came up might be against Wish.com and not you.
