Poor FNB service

I have been struggling over 2 months to close 2 of my accounts with FNB. I am not based in SA otherwise I would go into the bank to do this. I have sent numerous emails and made many calls to the bank to get these accounts closed. Everytime I call the bank I spend R18 per minute to make that call and every time they are unable to help me. I get told that someone from another department will call me back as the customer service department cannot help with my query. It’s been over 2 months now and FNB is charging me fees on my account. I refuse to pay these due to FNBs poor service. I moved all my accounts to FNB years ago because of the level of service they were giving but I would definitely not recommend this bank to anyone or open any accounts with them in the future!
