FNB is Terrible, stay away

Terrible service and I would not recommend your business to anyone. I logged a query regarding my revolving loan and it is now day 12 and I have not received feedback regarding my initial query. The last query I logged on monday ref ***. Firstly, I have to express my disappointment with the terrible experience and lack of customer support. For a company that has so many touchpoints, i logged my queries via email,call center,online portal, website, i get an sms my query is being attended to and then i end up having to call your call center to remind them that the query is outside of the 48 hours and no one responded to me, again just being told that they're going to send an email to the attending department. I received an email from Jacky Bela, as per the credit department she was liaising with, the information provided to me was incorrect and baseless, going against the terms and conditions of my revolving loan. Can I please get a competent person to explain the outcome of my query, I need to understand what is happening and not just some made up stories to get rid of a customer complaint, hiding behind the process and sending me an email, i need to speak to a human please. I dont need to increase the revolving loan, I am aware that this would increase my debit order, I need to know why i cannot access the revolving funds that has been paid back, more than 15%
