apexstocks LTD just told me I need to pay a $2,000 “cross

It’s yet another surprise fee I’ve never seen before. My account was verified. My withdrawal request was approved. Everything was supposedly done. Then,MT4 trading platform official website out of nowhere, this charge appears. I’ve asked three different support reps for documentation or an explanation—none could provide one. All they did was repeat the phrase “required for backend processing validation.” It feels like a scam at this point. I’ve paid enough. Every time I think I’m done, a new fee arrives with a new fancy name. Has anyone actually made it through all of this?
