TAKING MONEY FOR ACCOUNT THAT IS FULLY PAID

I have no idea what to do with you people anymore... I pay my credit card off, I call in January to find out the total owned and then it was paid in full but you still go and take R500.00 out of my account. I called on Monday spoke to Mpho Moledatsi [Email Removed] *** and I am not sure if you guys provide your call center advisor with the correct training but I d not believe you do. She then checked and advised yes it was a mistake and my moneys will be paid back into my account and will reflect within 24 hours that was Monday morning... That has come and gone... Pay my money back that you have stole out of my account I have paid you in full... I am not sure how longs it takes and advisor at Nedbank to type and email to confirm my account was paid in full again training is clearly a thing of need in the company. I want my money Today and I want a letter confirming the account is closed... That should not be to difficult for an advisor to do or I am expecting to much from my bank of almost 10 year to type a letter for a client?
