The chances of actually being because of OSBuddy are very very slim, I have yet to see someone getting rightfully banned because of 1:1 use of mousekeys or actually using OSBuddy. You can easily take leveling screenshots manually or use another client with OSBuddy. The fact that @Solution managed to get it unbanned from macroing shows that he wasn't the one botting otherwise they would've stated the ban was correct. Taking all of the this into consideration I came to the conclusion that you'll have to refund the remainder of the service plus the amount that the quashed ban devalues the account. I will get back to you with an exact amount.
