FBS is rejecting my withdrawl all the time

This broker is far from a decent broker. I ha traded for a few days and notice a wide spreads increase and big slippage as well. i decided to withdraw and then started the problems, they keep rejecting my withdraw claiming i used a different method for deposit, which is a lie, i used BTC to deposit and im trying to withdraw via BTC. Their support is a lie and is trying to keep my deposit!!! Don't deposit here!!! Choose a broker that is honest
