Standard Bank disappoints again.

I am very disappointed in Standard Bank services. I have a prestige account for the past 5 years with them and I've been paying for the account which includes a check card yet they have given me a debit card for the past 5 years which I can't tap and pay with, I can't do online purchases with, in this day and age. My card has expired 2months ago already. I've called their call centers three times already to get a check card and have it delivered as time does not permit me to sit at the bank for a card when options are more convenient now. But to my utter disappointment, the call center agents always transfer my calls to prestige banking and even they can't assist me. I've sent emails to my specific banker, to prestige banking email accounts and all of which get quarantined and don't go through. How does a bank of this scale publish email accounts that don't work and how is it that they have not noticed I've been using a debit card without asking me to change to a cheque even though I've been asking for many years now. I need answers and I need assistance. I've been thinking of changing my accounts but they can't even assist me in closing my account.
