Non response on querie regarding wrong interest rate.

FNB has my home loan interest rate wrong and are dragging their feet to sort it out. FNB promised me a decrease in my home loan interest rate if I do a salary stop order. This was confirmed by my HR department and also by FNB themselves who promised to action this when I phoned a month ago. When I enquired again on Tuesday, then suddenly they were not aware of this arrangement. Not only did they not action the promised decrease, but my interest rate is now higher than it was when I signed my home loan agreement. My interest rate is 0,75% higher than it should be. On Tuesday when I phoned to clear this up, I was promised that someone would phone me back within 48 hours. When I phoned today (3 days later) they still could not assist me because they were waiting for my home loan agreement to be sent to them. How does FNB homeloans not have access to their own home loan agreements? So not only are they taking more money than they should each month with a much higher interest rate, they also cannot help me when I phone and do not get back to me when they say they will. After ten years of me being a loyal customer, you would think that they would want to retain me. I think it is time to consider moving my home loan to another bank. Take home message: 1. the salary stop order apparently does not give you a decrease in interest rate..wish I had not bothered going through the process. 2. check your interest rate...do not trust them to work it out correctly 3. FNB really could not help me when I phoned them
