They even cited that the charge was for "mining fees." Are you kidding me? Mining fees for USDT. In short, I rushed to the live support, and we had a very heated argument that later made them apologize.
You probably won the argument because they understands the legal count charge as the case maybe if that was a centralized exchange you used.
They can't be afraid of the lawsuit with that small amount of money. Who would even dare suing them because of that small amount?

Besides, they did it innocently/ignorantly, so they have nothing to fear.
We're talking about reputational criticism here which I'm believed that a slight shit can ruin it all.
You also think you've been the only victim? How sure are you if they haven't been succeeding on you with the high fees all those while you've been using the platform which you probably might not have been attracted to your attention.
So if not of fear, why did they dialogue with you? It's simply because they're concious of the kind of your personality maybe so that you don't get them sued. That's the case why they played cool. Just get it right and believe me, they're still doing it to some other persons.

This is a deliberate act of theft from the platform. Would you please share their name, so others can take note.
I don't need to share the name to avoid demarketing them, and I've shared a while ago that it is a good broker. It's an Australian broker, and they are good and sincere in what they do. My observation later revealed that the broker itself was a victim of a middleman (crypto firm) handling their clients' transactions. I guess my argument with them changed the narrative, as they entirely changed their crypto payment system and now only charge the exact blockchain fee.
Do you know that making the exchange known will be of help to others who had been their victims without being known?
So I think it's necessary to share the name of the exchange afterall we do make discussions of specific exchanges here in the platform which we either recommend good or bad basically to the awareness of other users to take note.
You don't consider marketing empathy to exchange which are znot of standard and convenient for users.
If remarketing of such exchange will keep them head up for fair services of user, so be it. Don't keep such exchange on coverage.
