terrible service

I recently opened an FNB account, all my documents were sufficient to open the account. Now that they have me as a customer and my salary in my account my documents are not sufficient. They first said my proof of address wasnt sufficient so I sent them another account with proof. They have now frozen my account and the story keeps changing, they now say my copy of my ID is unclear. i have sent another copy and my account is still frozen and I have had no contact from FICA. quick to take your money but terrible service once they have it.
