Non professional response from private banker and No response from social media team

I just went through social media, no one is receiving response from FNB team.

I am FNB private client since 2012, my banking profile has 3 different addresses on multiple places...firstly i have no clue that how is that happening and why is there no synchronization.

Secondly i asked the private banker to update my addresses (provided the proof of address 3 days ago), and today i received an email stating that it can take up to A MONTH TO UPDATE THE ADDRESS.

This is ridiculous, even in 1980s it wasn't that bad (when there were manual posts and sometimes posts were only once a week or once a month to the head offices to share information) like now it sounds with FNB when everything is web based.
