Nedbank - the bank that ignores what the customer prefers

They have changed the app and online banking. Online banking now sends out proof of payer with full name on everything. I would prefer my Initial and surname. Opening the app my full name is plastered over screen. Easy to then try locking in with at least 2 tries. The old app was far better. Sending out promotional letters to my email addressing me by my given name. I gave them not permission to address me as such. I also asked at bank that no calls be made to me with sales, yet they cannot read or something and still calls to sell bank deals to me
