FNB private wealth

We have 6 business accounts with FNB and my personal accounts. We have had some of these accounts for over 10 years. We have not missed one debit order always pay on time and have an annual turnover of over R*** between all the business. Called them to apply for a business loan and comments where that we are a high risk account? How on earth does this work? It is a small loan for a business. The only thing they can do is to transfer the call to the next person then repeat. And this being with FNB wealth? I was in Tunisia for a business trip and they decide to freeze my account as they said my fica documents where old. Never bothered for 10 years but they wait till I am abroad to do something like this. All my business accounts are with them but Nedbank and Absa are the ones actually offering me loans on my properties. They give me a black card... debiet my accounts at the highest rates so that I can have access to these services then I get denied a loan on a Private Business?
