FNB not helping at all

I wish you guys could tell me when you would clear the balance on my account , last year i did an agreeement to settle my loan in 3 months in which i have done so already on the 4 of March 2019 i received an email with my Interim statement that in 45 working days i will be receiving a settlement later to no avail i havent received that letter up to until now are you telling me that you 45 working days hasnt elapsed , i did call FNB on Tuesday and the agent that i spoke to said the 45 days has elapsed she promised that she will send an email and i will get a response in 24 hours its been almost 48 hours still no response from you what must i do for this to be resolved this is really not seating well with me as i kept my end of the deal and you guys not even one person is willing to call and tell me what is going on , i think i have to report you to the obudsman as this is not fair at all i am not happy at all , it easy to deduct money from my accounts whats so difficult about clearing that stupid balance and send me the settlement letter , the account number is ********** 565734 and they is still a R5.562 that appearing in my balance
