Online Banking Error costing the client!!

I have been a client of Nedbank since 1983 and this the worst service and experience I have ever had!<br> <br> I logged onto online banking on the Friday the 6th of November to transfer money from my credit card to my cheque account. I received an error and the transfer did not go through. I tried the transaction 5 minutes later and still received the same error. Then called the support center and spoke to a lady who confirmed that there was a problem with online banking in the morning and all transactions had a problem. Then Saturday the two failed transaction I did went through my account and now I am overdrawn and still do not have the money for the failed transactions.<br> <br> I have also been charged for the failed transactions and will probably also get charged for being over my credit limit.<br> <br> Can someone please call me and fix the problem as I am out of money and needs to do some urgent payments?
