Absa surprisingly helpful

I had a deduction go off my credit card that I did not authorise after I had purchased something off the internet. I contacted Absa Credit Card disputes and they tracked down the company who had taken the money. They sent me an email within 2 days with the details of the company, how I could contact them via email and why they had deducted the money from my account. They told me clearly what I needed to say to the company who had taken my money and to report back what the company said. They were unable to reverse the money as I had signed a contract I was unaware of (the information they provided). I am hoping this will be resolved and my money refunded. Absa has been surprising in their help as they have previously not been very helpful.
