transactions on my accounts without permission

<p><span style="color: #555555; background-color: #ffffff;">Apparently someone deposited money into an incorrect account and that was my credit card. The manager at Roodeport called and I told him I had no such account and was a bit suspicious about the activity. He said when the money is available he would contact me to get permission to reverse the transaction and the bank charges. None of that happened now I have double bank charges on my account and still in the dark about what is happening </span></p>
