One thing for sure is, Bitsler won't scam you "only" for 150 XRP. They have been established since 2015 until now
they are scamming me for 150 xrp which is just stupid i worked with chat but i dont know if they hired new support people but shady as crap you can easly see what i am saying is rite. And just so you all know its impossible to request a withdrawl without a destnation tag but they sent it without one. There saying screw me and it my loss or job to try to recover when they made mistake
They still haven't replied your case, so you can't called them scamming you. Just wait for their reply (ussually they always give fast response). You are also didn't post your chat between you and bitsler's support whom told you tlit was your fault.
