Credit card mess up

Very very poor service. I app**** for a new credit card the Saturday. They said they will call me the Monday. I called them on Thursday and logged a complaint as I haven’t received feedback. They called me and I got my credit card application sorted out. Then they told me from head office that my card would arrive today (Tuesday 6 July). I scheduled my delivery last week already for today (Tuesday 6 July). The FNB app reminded me 2 times that my card will be delivered today between 2pm and 4pm. I work so I must arrange all my plans around this. Came 2pm, 4pm, nothing. Called them 2 times as well as the courier service DSV. So DSV says my card haven’t been delivered to them by FNB by it is already on the system. So FNB haven’t given my card to them yet, but the app sends me notifications twice that my card will be delivered today between 2pm and 4pm. This is absolutely ridiculous and such bad service. I am to the point where I almost want to cancel my credit card. Unfortunately this is the only way I can buy on credit at the iStore for the product that I want.
