Poor service from enquiries department

I visited my branch last year (probably around October/November), requesting that my bank statements be e-mailed to me. I filled in a form, provided my e-mail address etc. I am still receiving my statements in the post, with a nice message on the envelope stating that, do I know that I can receive my bank statements via e-mail. I've had numerous issues with this branch e.g. credit card application that was forgotten about out, home loan application that was cancelled without me being informed, teller not checking the date on the deposit slip. What is the point of having an enquiries section when issues are not addressed? I submitted a complaint on the Facebook page and I was asked if I found out why my statements were not being e-mailed. I followed the right procedure and I expected it to be done. Why should I now have to follow up? I have to take time off work to go to the bank, and the queues at this specific branch are always long at the enquiries section. Can someone please assist.
