Wrong debit from my account

Hi, I am feeling sorry to my self for banking with you guys, there was a debit from my account last night, i had to spend hour or more to get through all over the departments and not one person could explain me why did they debit and for what. really pathetic and unrealistic service .. my time and money and irritation i had to go through is undoubtedly one of the most, i cant believe going through so many departments and not one person could help. is this how you work guys ? i really feel like to use all bad words on the earth currently or directly escalate this issue to your senior management level.
