Poor service

On the 22 February 2022 at about 09h05 I missed a call from dsv courier ***) I tried returning it and spoke to someone called Nkolizi I told her that I was returning a call as well as expecting delivery of my bank card. She insisted that I provide a reference number before being assisted. I tried informing her that there's no message or sms so I won't have any reference. We then had a stalemate since she wants a reference number of which I don't have. Discovery bank contracted this *********** company and I'm questioning myself if I should bank with them when getting a bank card is such a nightmare.
