For me ComeOn is dreadful, negative just about every month, in fact think I have only ever got 2 or 3 payments due to being crap all the time. Tried to run a few reports as well and they don't work which has actually annoyed me now
Had the same with Bet24 years back, was sending loads of players each month but each month the players just won and won and won
So which brands just offer no results for you each month?
