***** or no *****? HELP!!!

On the 18th of March a R300 withdrawal was made on my credit card. Apparently, after spending 2 hours on the phone with the call center and numerous division within - Abongile Mafanya told me that a withdrawal has been made inside the bank (just for the record Mr Mafanya was very kind and even gave me a personal call - all the way in China). Now the thing is I am in China and naturally cannot make a withdrawal in Sea Point. Mr Mafanya, from the credit card division, then told me that he would speak to his supervisor, because they'll have to block the card permanently if they are to launch a formal investigation. However, I need my credit card and cannot open a new one from all the way in China. I can't close the account because of potential *****. My theory is this. A couple of weeks ago I made a complaint with Hello Peter about an insurance policy Standard Bank charged me for that I never signed up for. This money was returned R296 and reversed on the 18th. The transaction name is \Standard *4018Marsh". What I would like is a full investigation without closing my credit card account. ID: ***"
