Poor Service

I'm really disappointed. I had updated my personal details at a branch with a very helpful consultant and was told the update would reflect immediately. I recently received an email with my statement and saw that my address was not updated as I was informed. I sent an email to query this and no one has contacted me about my query. Instead of receiving a call about what I queried, I was offered a legal protection policy. I informed the consultant on the phone that I am not interested in the offer, can I be assisted with updating my details. I was told I need to go back to the branch and query this. I am currently working and I do not have time to visit the brach to do something I was told would be done immediately. This is a major inconvenience as I need my updated address as proof of residence for a really important document. FNB is quick to offer legal plans and funeral policies that I am really not interested in but take a long time to resolve issues. I'm really unhappy about this and I hope someone contacts me regarding a solution. I am not prepared to go to the bank again. If this is not resolved, I will need to change my financial institution which I'm hoping not to do.
