Help Yourself to my money Mastercard

My June statement reflected a "Cash Finance Charge" of R67.83 and my July statement R51.91. I phone the card division to query these charges. After a long frustrating conversation the person could not help me and lodged an enquiry Ref. No.***. Said I could phone back on 7 July. On 5 July I receive an email attached to which was 6 month's of statements. No explanation. I then discover that I have been charged R190 for these statements! At no stage in my conversation did I ask for statements and it was not suggested. The call was apparently recorded so this can be checked! Why would I want these statements when I receive statements monthly? To add insult to injury I am still none the wiser why these charges were levied! I want to know specifically what transactions resulted in these charges. I also want all charges including the statement fee reversed.
