I recently opened an account "money on call" in error, so I called in and tried to get the account cancelled, I was told to transfer all the money from that account to my cheque account and that was done....the account couldn't be closed, I was then told the account would be close on Monday 04/09/2018, I called in again and the account still couldn't be closed... later on one of the consultants called me to inform me that the account still cannot be closed from your side, I must go to a branch and close the account there, however this will not affect my account at all, to my surprise almost R9.00 was debited from my account because instead of this money on call I decided to use Savings pocket, now my question is since the account was opened online, why do I now need to go to a branch to have it closed?? and why did the consultant tell me that I can leave the account open and it wouldn't affect me in anyway yet I have R9,00 taken from my account, if I leave it it's going to charge me everymonth
