***** department with no help

On Friday have reversed an unauthorized transaction from LinkedIn and on Tuesday they decided to debit again with a higher of R7029.96 of which again I did not authorize nor agree to, reported the matter and was told they can not reverse as is it was the second time from the same merchant, I was advised to report to ***** department and today ***** department is telling me they cannot assist me as I gave my card details to the merchant of which I did not, my credential have been compromised and all I get is we cannot assist you in this regard, was wrong to believe that my money is safe in my bank, now my R7029.96 is gone with this scrupulous merchant called LinkedIn and have bills to pay,,,, am closing my business cheque card immediately with standard bank they just a useless bank, how can your own client suffer at the hand of ********** transactions and you just say we cannot help you in this regard...
