Bad service at FNB Maponya Mall branch !!

I'm so frustrated by FNB. By law if you have a loan or owe any financial institution like a bank you can request a statement from them of what you owe ESPECIALLY IF YOU DO NOT HAVE THEIR BANKING APP and one must be granted to you. I went to FNB Maponya mall and the teller was just not willing to help from the moment I explained my matter regarding the loans I have he exclaimed " Yooo" imagine what kind of service is that!? I then asked him what is the matter he then said " your matter is complex because we need to call the loan department" i asked " is calling the loab department requires a lot of effort like lifting up a building? Hence i was lost . FNB if you do not want us to pay what we owe you it's fine, you cant hire people who do not encourage payment of debts and entice or advice a way of doibg so without being rude or seeming not interested at clients. Even when one calls you we must have your app to access information that will assist us in paying you. Everytime I call or visit FNB branch my matter is always complex it's only one teller who got it right and encouraged me to pay my loans now that I want to pay its even a storm for FNB to give me a simple statement of my accounts that I owe!! Where should I go can someone from FNB contact me coz I'm tired of visiting your branches and you send me from pillar to post.. but you can send me thousands of emails about paying you!! My number is ***!
