Not getting back to me

On the 6th of March a transaction of a R1 047 went through on my credit card. I immediately phones to have it reversed as the company had no authorization to have debited my card. The consultant warned me if I receive any SMs of further transactions I must phone them immediately. On the 8th I got a sms that my account was in overdraft and had to make a payment. I phoned and was told on the same day another transaction of R1 077 went of. No SMs was ever send to me to have warned me about this. A fault from Standard bank's side!! They apparently could not reverse the transaction and had to file a dispute. The consultant was not keen on helping me and just forwarded my call to speak to someone else. I was told to fill in a disputed form. Went to the standard bank opposite in a sentrum of Menlyn. There they did not even know what I should do. Eventually I phoned in got a form, filled in at the branch and had them fax it. I asked for confirmation, still today nothing. I faced my own form with a letter stating Everything what happened that that this was ***** from the company as I had not signed anything g etc. still no one from standard bank came back to me. I'm to afraid to pay my cc
