Requested to have account closed ignored.

On Saturday (17th October) I went to Nedbank Northgate Branch, to close my Cheque account. I was assisted by (Teller) Caroline & she took my card & destroyed it, closed the services(online & cellphone banking) &advised that she will forward to the relevant department to have my account closed. <br> <br> Now to my Surprise on Monday (19 October) the account is still active, After waiting for more than 40min, filled in all the paper work! Then I called the contact center & spoke to Gugu, spent more than 20min on the phone & was promised that she will send a notification once the account is closed on Monday. On Tuesday (20th October) I called and spoke to Jenice who confirmed that my account is closed, But when I checked my account today via cellphone banking it's still active. I have used my airtime, spent more than 2 hours calling and holding from Monday till today. My Account is still ACTIVE. <br> Mary from Northgate sent me an email informing me that the account was closed. But I can still login to my cellphone banking (which is supposed to be closed) and can view balances and transact. DOES IT TAKE A WEEK TO CLOSE AN ACCOUNT!!! <br> DOES A CLIENT NEED TO GO TO THE BRANCH AND CALL EVERYDAY??
