Worst banking division in SA

At this point we have no idea what to do anymore. We were unhappy with the poor service and lack of response we kept getting at FNB with regard to queries and additional services so we decided to switch our home loan to another bank. Our attorney has been requesting the cancellation documents from fnb for well over a month now and it is simply impossible to get hold of anyone that will provide it. At first the islamic banking division told us to contact the home loans division and after doing so we were again told to contact islamic banking. After this they simply stopped responding to us and our bond registration attorneys. Its now impossible to get hold of anyone that can assist us via telephone and it seems that fnb employees just don't respond to emails. Its very disappointing and quite clear that fnb cares very little about developing and growing their islamic banking division since I've never come across a worse department and one that is as hard to deal with as this one. We are now at our wits end and so much of our time has been wasted on this. I will never use this bank again.
