FNB Bad Service

After thinking that FNB was a bank with excellent service,I decided to open an account ONLINE. Thats where the problems began. After sending through ID and salary documents for a tiny overdraft, I started getting more messages to do it again and again. Then I was told that the overdraft was rejected because I did not supply the documents required. I sent through these documents at least 3 times, once even to a consultants (Debs Edwin) own email address. Still I received messages. I had to call them to find out if a copy of marriage certificate was needed since my ****en name was on my old bank account. Frustrated, I asked them close the account. Now, I am told I have to come into a bank to close the account due to security reasons! Surely FNB should be more security aware when one OPENS an account, and surely CLOSING an account BY TELEPHONE with all their security questions, should pose no risk at all?! Really bad service!!
