Standard Bank online system very worrying

I went through the process of applying for a Mymo account on the STD B app. Halfway through, the screen goes black and throws me out of app. I try again and it takes me through, but no email or sms confirmation is sent. After a few hours, I phone helpline and even after telling my story as clearly as possible I am erroneously put through 3 times until at last I spoke to L who listens to my story ,checks my account and says there is no record of my application. This is very concerning as I was required to scan in ID as.well as physical scan of my face, yet Standard Bank has no record of it and cannot tell me where my data has gone. L eventually puts me on hold on for ***** dept, I get cut off, and after phoning again, and telling my story for the 5th time, I get told he will put me through to application ***** , promises to hold on with me and then I get cut off. Now they are closed. Standard Bank's system does not inspire any confidence, each time I am required to give my information, but they can't tell me what has happened with it.
