Nedbanks Lack of Customer centricity

So it’s Friday and Nedbank have blocked my account due to FICA. I use to work for a bank, I get it. But why ask me to update my details if you don’t use them, why didn’t you call to ask if my details have changed, why do you block my account and tell me that I can’t use MY MONEY for the next 48 hours. “We sent you multiple SMSs” so you couldn’t ****en call the number you have when you realised that the SMSs were not working.
