NO FEEDBACK on credit card *****!!

I am so frustrated!!!!!! I experienced credit card ***** and dealt with not so friendly person that assisted me and when I explained there was money still missing she insisted I was wrong so I left it just to get some money from the whole situation. Then she reimbursed the amount and then on 4 August statement it stated an amount on my statement. On the 12 AUgust all the ********** monies were charged again to my account!!!! none of the call centre staff can help me and now I have emailed Gwendie Oosthuizen. Someone please help me as my account is not over the limit....no feedback since last week. I need to know why this has happened.
