Over Limit Fees

I have been charged over limit fees on five instances this year
I have requested exact dates on which these fees are applicable and how much I was over my limit as I do not agree with this.
I have made calls daily for the past 6 working days, and I have spoken to approx 6 different employees.
No one is willing to release this information to me, and I cannot understand how they can charge the fee but not be willing to substantiate their claims with the required info.
By far this is some of the worst service I have ever received
