I've recently bought BA (subscribed annually

But unfortunately,refund is not possible which is ridiculus!!
The most of the features don't fit my needs apart from the ladder.
Today,I've tried sending unmatched bets to market by using manual bets and I've set the odds and stake,clicked back.It was already matched!I mean it's manual bet section and it has a back/lay button.But when I click the back button next to the manual odds section that I've just adjusted,it backs the horse at the current price.
I'm compeletely dissatisfied with the software and can not get a refund,so funny!
