STANDARD BANK. THE WORST BANK AND CEO!

I have been on here before. I am elderly and to get to the nearest Standard Bank involves a 40 kilometer trip. I asked the bank to change my email address but they refused unless I went into the bank. I explained my difficulty in getting to the bank and they then sent me screeds of forms to complete and return with a copy of my ID and rates account. I did what they asked but they still refuse to change my email address. I went into the bank at Robertson but there was a waiting queue of 14 people. As I was reliant upon a lift I could not wait. I cannot load the Banking app on my new phone as my new address is not registered. I cannot shop with the old app as the confirmation is to my old address. I wrote to the CEO for help but he has ignored me an does not answer.
