FNB worst service ever - just wanted to update my address!?

Worst possible service i have ever experienced. Went to FNB branch at Northgate just to update my residential address - volantarily mind you. Was "assisted" by a person called Collins who outright refused to help - was dismissive and rude. I asked for a manager to escalate the matter only to be given further run around. Produced multiple iterarions of proof of residence ALL of which were summarily rejected. I am speechless and left infuriated by the attitude and lack of care/interest to help - as if i would need to lie over something so trivial - treated as a **** or ******** as a result. I will be reviewing who i bank with going forward and will not recommend FNB to anyone. Banks should take care to remember that it is us who gives them business and that they are not doing us any favours! Keep the incorrect details for all i care!
