I had the same Problem two times … sorry to say that but im sure you bought dupped tix and the system recognized them, not from TradeOrIShootU, but he bought from a dupper or his seller from a dupper. Sorry to say that but nobody will refund you
The system punishes the legit Player NOT the dupper. The only advice that i can give is buy only few tix from low Level or low stats Player. As example buy only up to 50 tix from a Level 100+, 100 tix from a Level 200+ and more from higher stats account etc...
The dupper loses their accounts after the trade with dupped tix so they must make a Profit OVER the lost account. It is better to buy a small sum and wait one or two days, add the guy and you will see if your tix stay or not - even if the reposter cannot help us.
