Charged on reversal

I think it is unfair that a person gets charging for reversing an authorized debit order, why would i reverse something that i made a commitment to? It is so frustrating that a person must go through this mess and to have your Bank charge you to reverse is ridiculous and I was told they do not charge for reversing a couple of months bank now two day ago i had to reverse via phoning in as the amount was over 260 i go through my transaction history i see i was charge like that is wrong and unfair this is an ongoing thing and it seems like the bank does not care.
