FNB has ignored my previous complaint

I wish to make a complaint against FNB. It had been a week now since I last made my complaint. As of yet my problem with FNB's Online Banking service has not been resolved or addressed. I have since tried again to reset my password online via FNB's Online Banking service and it still does not work. I am becoming increasingly disillusioned with FNB&the longer this takes to resolve the more it is costing and inconveniencing me as I have to use cellphone banking to check balances and make payments. At this time I am not happy at all with FNB&feel that they are beginning to reflect the poor service in general in South Africa
