Monthly charge statement

I have been receiving my monthly charge statement for my cheque account the last 3 months. I have made enquiries at the bank which they indicated they would not be able to assist other than send a request to the relevant department. I have called as well of which I got the same response form the call center agent. Via email I got a reply that my case has been reported to a consultant and would call to provide feedback as soon as possible with case number C- ********** 4. To date I have not received any feedback. I am trying to understand why my bank charges have been excessive and have charges which I do not know what they relate to and keep referring me to the charge statement which I have not been receiving.
