Just do what I do, stop spending money here.
In April I donated £672. 81 then in May £622.80 haven't really counted further back but not the point. When you stop spending money, because of his poor decision making, maybe his attitude will change.
I'm glad he can afford to lose the custom.
Maybe your armour was bugged and you too should of noticed a big stat increase...... And come and reported the increase before you rushed ahead and socketed your armour..... Because yes, its your fault. Not his.
Good look sorting it out, I've come to concede that your wasting your time. As the man thinks a 14 mc increase from a 148 weap (which is easy to upgrade) to a 166 (which you can't upgrade)?. Is some how a huge stat gain that should be reported.
But good luck resolving your problem, I'm sure in 6 months time he will add the content so you can upgrade. Then your armour might be better than celestial like the weapons are.
