Cannot even change my email address

3-4 months ago I advised my private banker that I wanted to change my email address. she said I couldn't do it on the internet site ( why ever not??) and I would have to go into a branch. I did that and they confirmed that it would be changed on all their systems. that was about two months ago and I continued to get statements to my old email and I could only log onto internet banking with my old email. so I spoke to Chantal in Internet banking. She said only IT could change it and she would send them an email and copy me and my private banker. Never heard a word and nothing changed. sent an email to Internet banking and was told I would have to go into a branch. last week phoned internet banking again and was told " oh yes but its fine now I can see it was just changed yesterday ( after three months) next day my credit card statement arrived at my old email and I couldn't log on to internet banking with my new email Its just un believable in this day and age Next step is to phone FNB !
