Disaster to change signatories

We have now been foreword and backwards for two months to change signatories on our business account. Got completely different advise from the Montana and Menlyn branches. Early November we were advise to send all the forms to [Email Removed] which I did on 4 November. I received an auto response to say that my enquiry will be addressed in three business days. More than two weeks later and still no contact from FNB in spite of four calls to the call centre and the case being escalated to two team leaders. Every time just an empty promise that someone will phone me back. Indeed very disappointing. I have lost my faith in FNB and will advise my fellow directors to close this account. Luckily my private account is green where I get excellent service.
