Redbus — I want to do money transfer from redbus wallet to my bank account

I am using red bus app for bus ticket booking. After a long time red bus gives some discount as cash back on ticket booking, so i got also cash back of discount money which is appears on my red bus wallet. But sorry to say that there is no option for transfer my wallet cash to my bank account. Therefore i request to redbud team to please return my wallet amount to my bank account.
