High Bank Charges

I switched my account from a savings account to a cheque account earlier this year, because my bank charges were high. But its been a nightmare ever since i switched over, I am still being overcharged on my cheque account. It took them almost a month to rectify incorrect bank charges on my account, which i was initially told they'd attend to my query within 24-48 Hours. I was overcharged yet again for the month of May, the branches and the call can't both help, they say i have to wait for a response from the email i sent. Is this something that I am going to be dealing with every month ?
