Expensive lesson to be reminded of.
Sucks, but I don’t think you have any chance of getting your gold back considering the circumstances.
I’ve also seen someone advertising the TCG mounts recently. Also thought “too good to be true”. Could very well have been the same douche.
At this stage, I think it’s pure folly to engage with an offer like this… Only because we will most likely see these mounts on the Trading Post. No point in risking being scammed.
