Unsatisfied customer - Cards cancelled without my consent

I have been a Standard Bank customer for more than 20 years. My debit card & credit card is due to expire in April 2022. Went shopping today (March), only to find that Standard bank cancelled my current cards and ordered "new" cards for me, for delivery to my branch. This means that I cannot withdraw money, cannot buy anything using my current cards or get fuel into my car. All over a month-end period. I went to Standard Bank, Kollenade, for assistance. Waited in a queue for almost 3 hours before being assisted. Was told that someone made a mistake - sorry. My new cards will be delivered to the branch next week (at which time I will have to queue again for 3 hours). Very unsatisfied customer!
