I have been a client for many years

I have been a client for many years. My business account has now been frozen because FNB did not have my correct email address. I eventually completed the relevant forms and sent it to FNB. I have now been trying for days to get my account back to normal but to no avail. During telephone conversations I have explained my position and asked FNB to make this a priority. This has caused a huge disruption in my business which was unnecessary and I am still sitting in the same situation. The communication and actions from FNB was not up to standard.
