Terrible bond policy

I approached FNB for a further lending amount on my existing bond loan. They offered me this but on a higher interest rate than my existing rate. This meant my existing bond plus further lending will then be calculated on this higher rate. Their response was they cannot due to their \pricing strategy\". Is FNB motto not \" how can we help you\", seems they helping themselves. Had I not asked for a further lend, my bond would remain on its existing interest rate. Is FNB seizing the opportunity to make more money from me? Not even meeting me half way on the rate! Another opportunity they took: I was told in order to complete the further lend application I had to transfer out all excess money in the bond account to do calculations! NO FNB, you just wanted to calculate interest on a higher balance outstanding!"
