Disappointing service from FNB

I am completely disappointed and annoyed with FNB regarding the service and misrepresentation received from them ito my home loan application. In summary, I agreed to move my account of nearly thirty years from Standard Bank to FNB (in effect, I agreed to give FNB new business). Following this, I was continually harassed to move my debit orders (phone calls, emails, sms). My debit orders were moved way before I was in a position to move my salary with the result that debit orders were then rejected. This has now negatively affected my credit score. To make matters worse, my home loan is being declined because of this. The above situation is totally unacceptable and I will now proceed with the complaint process as well raising my concerns on the necessary social media platforms. I will also be seeking recovery of the bank charges incurred over the last five months. Standard bank was offering me a home loan and because of the persistent follows up FNB to consider them as the service provider, I moved banks and now their competence as caused me to be declined. If you look at my credit ability you will see there is no reason for my application to have been declined. Now when I asked for an answer, it takes weeks to get a response and it is just oh we need to motivate and look into it. When they wanted my business they didn't need to look into anything. I now have to pay extra bank charges for their useless private banking services. Talk about "how can we help you". Respond first!
