Unable to get accounts updated

I have a cheque account, savings account, UCount, petrol card and a credit card with Standard Bank. Apparently none of these are linked when it comes to updating of information. Every time I need to register or apply for some or other product or a simple thing like changing my cell number I need to go to the branch to do that.<br> <br> For proof of residence and to supply my ID I can understand(FICA), but to change my number? Not to upset myself, I went to the branch in Centurion and after I moved to Gezina to update my details and after MANY assurances they told me everything is fine and all my accounts are updated, but now I cannot get my OTP or register for a simple thing like an insurance quote on the website. <br> <br> I'm a working person. I cannot go into the branch every single time I need something, that's why there is internet banking? Is there not one single person in Standard bank that can do their job right and do it right the first time? <br> <br> This is not the only time they didn't come through for me, but that's a complaint for another day. I'm also thinking of starting a business in the near future and I want to use Standard Bank, but how can I if this is the type of service they give?
