It doesn't let me make a transfer, it says this account is not allowed on the internet... I have to use Bitso to buy USD crypto

Why when I buy a currency on Binance with a credit card is its price significantly higher than the quote? For two days it has been doing this to me. For example, the current price of the IO.net currency was 3.01 euros. When I click the estimate is the same. But when I pay Binance tells me that the price is 3.06. The difference is huge and it has been for a few days I don't know (this is an example, it does this to me for all currencies, pepe = 0.00000174 and when I buy 0.000002015 is totally uninteresting) and I don't count the transaction fees which are clearly written. @Binance Customer Support @Binance France Live
