POOR CUSTOMER SERVICE AND AFTER CARE

So disappointing, thinking of moving all my accounts away from FNB, Personal as well as business, it has been almost two months that i am requesting for a paid up letter for an account that has been settled, been transferred from department to department, no one can take responsibility to assist, not even to mention that with having certain accounts give you certain benefits. This is absolutely unprofessional not even mentioning staff that cant take ownership and assist with a problem that is on their side. Cant wait to hear what the excuse will be this time, or what we are waiting for this time... or what department i should phone this time. Maybe the FSB will be able to assist me in this regard?
