Discovery credit card false promises

I signed up to discovery bank for the benefits joined with vitality. Part of the benefits require a credit card from discovery. When I signed up on the app it did not give me the option to apply for the credit card. I have been patiently waiting as I have been told it would become available. Yet my girlfriend signed up before me and got the credit card.

There are no email options but only a call centre which I have called and asked them to escalate it with no response there after. Its been well over a month. I don't have time to sit with a call center waiting for them to figure out how to fix this. They were pretty adament that I cannot apply for the credit card because I didn't do it on application which as I explained was not an option on my app. I also experience issues with the app which have been subsequently fixed. Just no idea why you advertise the benefits but then do not allow me to apply for the credit card.
