Extension of home loan bond term issues

My wife and I have been trying for 2 months to get Standard Bank to extend the term of our access bond in order for us to be able to do further renovations to our property.

Unfortunately as much as we have tried repeatedly via all channels to give Standard Bank Home Loans the opportunity to keep our business it seems that they do not want it. We have now resorted to applying at another bank and will move our home loan there if the other bank can give us an offer before Standard Bank gets themselves in order (if they ever do). And possibly our other accounts.
