So you lost almost 400 dollars on this trade? This is crazy
It's impossible. What a pity for you!
Have you tried contacting their customer service and asking for support? In this case, in order to get the most detailed and accurate explanation, there is no other way, you must get the answer from them.
I have never used it, but for regular exchange services, they will show the estimated value you can get, have you checked it before making exchange? (Maybe you didn't consider it?). Can you provide a hash here to review the transactions you made? Recently, I use Uniswap, although I think the fee I have to pay is expensive, it just stops at a maximum of 60 $ (Expensive with small transactions). But it is impossible for a trade to cost you nearly $ 400. It's ridiculous. You need to contact them immediately!
There could be another cause as well, but I'm not sure. I used to deposit more than 30k Thrive coin into an exchange (Kucoin), but when that amount shows up in this exchange, it's just over 22k. I asked for their support right after. And the answer is that the amount of Thrive coin I lost is the transaction fee that I have to pay to load into the platform (I mean pay miners). That means I have to bear transaction fees other than ETH. I don't know what currency you swap and how it works. But the same thing might have happened to you. In short, you need to ask them
Additional, I cannot find LIGHT on Pancakeswap
