Pathetic service as usual from FNB

My banking details were updated incorrectly. I was never contacted regarding this, nor did the person loading these details bother to check. Now I'm sitting with unpaid mag tape items, which I've been told will be refunded to me, to date nothing has been done. I've escalated this matter via email, and kept getting passed around like. Nobody has contacted me back as per the conversations, nobody will take responsibility. I will gladly published the emails. There is no point in paying a broker fee if the broker can not escalate the matter and get it resolved. This is the customer service that we can expect from FNB, doesn't suprize me if you look at the reviews here. What amazes me the most is, if the customer owed FNB money- it would have been escalated very quickly, but when FNB owes the client money, they take their sweet time. FNB talk so much about service, makes you wonder is this the service we can expect.
