As I told before, BestChange Should talk with both sides and come up with a solution. Why I am expecting a solution from The BestChange? Because They Provide service, They earn money. They have to take liability if the user got scammed by their partner exchanger. The UnioChange working with The BestChange for a long time. And They are aware of their unprofessional business.

You could tell me that, How can they know that UnioChange Will do business unprofessionally? Do you think this is UnioChange's First case? Nope. Not at all. They have had more cases before. Where was The BestChange team that time? Why do they do the investigation now? Why they didn't investigate before when the First Scam accusations were raised against The UnioChange?
Don't you think The BestChange team is liable for this? I didn't ask them to pay users. I asked them to talk with both sides and come up with a solution. Delist The UnioChange From their site is not going to help OP.

Here is another case. it was in 2020.
