place limit orders to reduce fees

Wow good afternoon blessed people.. look I am outraged by the trade fee that Binance is charging.. I went to trade with 14,154 and they are giving me 13,665. Wow, 500 reais in fees, this is a robbery and don't block me because I have been a customer for a long time and I have the right to complain as an investor. I am already losing in the amount of 5 thousand BRL and I still have to suffer this abuse, it is a shame that a brokerage firm of this size and that already makes large profits does this to small investors..
