Im amazed this thread is still rolling on approx 3 years later, has over 6000 views and KBC have taken no action.
I ended up closing my account and then subsequently moved my mortgage to another bank that does offer paperless statements.
Funnily enough when I was asked why I was closing the account and I told the person at the hub the reason was because KBC couldn't/wouldnt surpress statements and go paperless.
I was told that it was in the pipeline, paperless statements would be rolled out shortly and I shouldn't close my account for that reason.
That was about 2 years ago.
Obviously the person at the hub was `mistaken'.
