You're right I'm not playing RuneScape at the moment (thank god) but you get the idea. It's an additional helm (200 points) yes, but it's still an extra order so you can't bring up the 25m here. You also stated you want it done asap, servicer knows the game and gave you a price. Now stop creating threads in RAS as no scam occured, thanks.
EDIT: Just spoke with rune and he said he gave you a price for a void set + a fire cape, not 2 void sets.
