FNB Business Banking Fiasco

To whom it may concern at FNB Business banking. I have a very basic issue to resolve on my business account. My private wealth personal banker sent me a number to dial. My first I dropped after 8,45 minutes of no answering. My current call has now been running for 52 minutes with no answer. The personal banker tried to call another number with no luck either. He has now recommended that he writes an email himself to them and copy me in. This has not happened either. FNB, if you are okay with a person waiting an hour to get through to your call centre then it is clearly not worth doing any form of business banking with FNB. My number is ***. I expect a call from you by 12h00 today or I will move my business banking away from FNB today. This is not acceptable.
