Nonsense of a bank

I changed my pin on the Capitec banking app in the month of November 2021 and when I try to use my card on the ATM, the new pin is not accepted and so is the old one. But when I login on the banking app, it takes the new pin and on my cellphone banking, the old pin is being accepted. I am so disappointed because the only way I can have access to my money is through sending myself an ewallet which is so inconvenient to me.
