Wish complaint: Unauthorized purchases for items not shipped or refunded.

Wish.com has stolen over $100 from me through the event of unauthorized purchases which I immediately caught and immediately reported.
I got a message telling me the funds would be credited back to the original payment method. I have spoken with my financial institution and have checked daily for a month or more for the refunds and they do not exist. They sent me messages saying the money was returned which is a lie. I can prove this as I’m having my cracked home button repaired Monday and can prove with screen shots that they are lying and my financial institution can verify that there have been no deposits from Wish into my accounts. I’d like to know how to turn them in . Who handles Better Buisness Bureau complaints in China. I’m considering starting a class action lawsuit. They have not refunded the money, I have not received the unauthorized purchases by mail.. I can prove all of this. Please help me. I’ve spent over $600.00 since the beginning of the pandemic. This is not the only time they haven’t followed through. They also marked an item I ordered as shipped and I assume the piece of plastic they sent along with a purchase that I actually did order was considered as the finger puppets I ordered. I opened the package it was one item I actually did order and the other thing was a literal piece of plastic that I assumed was trash so I threw it away later to find that the finger puppets I ordered were marked as shipped when in fact I NEVER received them. I received a piece of plastic that I already had thrown away. Also there are products I ordered that were in NO WAY as described, products that I ordered that do not function properly such as the two Bluetooth wireless headsets which I most recently ordered but am taking the loss instead of eating my time shipping the items back to China and also a Android phone that I paid over $100 for that wouldn’t even charge. I am mostly upset that this company is lying to me saying they have refunded the unauthorized transactions when they haven’t and I have various ways to prove it. I need the proper info to turn them in for fraud. Please email me if you can help [email protected]
